+1.56 (Sep 8, 2009)
+ - Fixed authentication errors caused by invalid base64 encoding.
+ Thanks for dozens of people who reported this and even submitted
+ patches! Sorry it took me so long to get this fixed :|
+ - Updated authentication code so it would try both AUTH PLAIN and
+ AUTH LOGIN methods before giving up. This should make it even
+ more robust.
+ - Detect <!DOCTYPE in first line of the message body as an html email too.
+ - Added command line option to force sending message as either
+ text or html (also allows a manual content-type header).
+
+1.55 (Dec 13, 2006)
+ - New command line option to specify a local bind address. Useful on
+ machines with multiple IP addresses.
+ - EHLO should never send "localhost" now. I Added a new function
+ called get_hostname() that does several new checks to get the system's
+ hostname. If all else fails it will send it's own IP address.
+ - Added a new command line option, -o fqdn=FQDN, that allows one to override
+ the name sent after EHLO.
+ - Small change to how the timezone is sent, it was triggering spam filters.
+ - Windows executable now has TLS support enabled!
+
+1.54 (Oct 28, 2006)
+ NEW FEATURES:
+ - TLS support is finally here! See the -o tls=[auto|yes|no] option.
+ To enable simply install the Net::SSleay and IO::Socket::SSL modules.
+ NOTE: If you experience errors related to TLS, PLEASE UPDATE your
+ Net::SSleay and IO::Socket::SSL modules before reporting an error.
+ I have already found inconsistancies with older versions.
+ - Updated the "-o message-header=HEADER" option so that you can use
+ it more than once. Additionally you can now use it to override message
+ headers that would have normally been generated by sendEmail. This is
+ particularly useful when a custom Message-ID or subject is needed.
+ - SMTP authentication now supports the SASL PLAIN mechanism along
+ with the LOGIN method.
+ - New optional way to specify username and password with the -o option.
+ - If a username is supplied with -xu, but a password is not specified,
+ sendEmail will now prompt for one rather than exiting with an error.
+ BUG FIXES:
+ - Fixed an annoying bug that made some MUA's believe there was always
+ an attachment when there wasn't.
+ - New base64_encode() function that fixes a bug that was causing certain
+ usernames/passwords used with -xu and -xp to not work properly.
+
+1.53 (never publicly released, changes merged into 1.54)
+
+1.52 (Feb 19, 2005)
+ - Fixed the bug that prevented sendEmail on Windows and Mac systems
+ from working properly. Thanks to the many people that reported that
+ bug! Sorry it took me so long to fix, I've been working on my new
+ anti-spam service for businesses at http://www.dotclean.com/
+ - Allow null command line arguments. For example -u "" should work.
+ Thanks to Mike Nadeau for pointing out that bug.
+ - Print shell escape codes for colored help on everything but Windows.
+ Thanks to Offer Kaye for that tip. If this causes problems anywhere
+ please let me know!
+ - Changed default mime-encoding header to "application/octet-stream"
+ rather than "base64" when sendEmail can't guess any other content-
+ type to use. Thanks to wwp for that patch.
+ - Added a -o message-charset option to specify the message body's
+ character set. Thanks to Jei for letting me know not everyone
+ sends messages in iso-8859-1 ;)
+
+1.51 (Dec 02, 2004)
+ - A few alarm() calls were being called on Win32 systems which doesn't work.
+ - Added -o message-format=raw option to allow sending of raw pre-built email
+ messages. Thanks to Lutz for the patch!
+ - If the hostname isn't found in common environment variables it now loads
+ the Sys::Hostname module and uses it to get the hostname. This should
+ work properly on more platforms now. If calling this module causes
+ anyone grief please let me know!
+
+1.50 (Sep 30, 2004)
+ - There has been a long standing bug where sendEmail could tell you the
+ remote server accepted the email when, in fact, it had been rejected.
+ This is now fixed.
+ - Changed the textual output of many debug messages.
+ - Added a Message-ID header to each message sent.
+ - You can now specify multiple to, cc, or bcc recipients by separating them
+ with either a space, comma, or semi-colon. Previously it had to be space
+ separated.
+ - Replaced the connect function with one from the IO::Socket library. The
+ IO::Socket module is included in default Perl installations, so this change
+ does not create any new Perl module dependencies.
+ - When sending to multiple recipients and one is rejected by the server
+ sendEmail does not abort as long as at least one recipient was
+ accepted.
+ - To, CC, and BCC fields can be specified in the
+ "Brandon Zehm <caspian@dotconf.net>"
+ format and it will populate the appropriate fields in the email message.
+ - All messages are now MIME encoded, even simple text ones. This makes the
+ program flow much cleaner.
+ - SMTP Auth is now supported with the -xu and -xp command line parameters.
+ - You can create multi-line messages on the command line now by putting
+ a '\n' into the message specified with the -m parameter.
+ - Always use +0000 for timezone, and get the current time from gmtime()
+ rather than localtime().
+ - Added some color to the help and documentation if the shell is Bash.
+ - It now aborts with an error message if all file attachments can not be
+ found before connecting to the remote smtp server. Previously if an
+ attachment specified couldn't be opened it would simply send the message
+ without the attachment.
+ - Allow a single custom email header line to be specified with
+ -o message-header=HEADER
+ - Add a -o timeout=SECONDS option so you can set the timeout used for all
+ network reads and writes.
+ - Added ability to specify a "Reply-to:" header with -o reply-to=ADDRESS
+ - Added ability to read message body from a file with -o message-file=FILE
+ - Added a lot of new documentation available via --help TOPIC.
+
+1.42 (June 06, 2003)
+ - It was possible to send bare CR's, so I fixed that now. (Thanks to
+ Jared Cheney for the bug report)
+ - Patch from Jared Cheney to add the MIME-Version field to conform to RFC1521
+ (made attachments work with more mail clients)
+
+1.41 (Apr 22, 2003)
+ - In some cases bare LF's were *still* getting sent, so I think I fixed it
+ right this time. (Thanks to Buddy Nahay for that bug report and helping
+ me test the fix!)
+ - Fixed bare period encoding (it wasn't working in all cases either)
+ - Changed HTML detection to require the <html> to be at the beginning of
+ a line. Otherwise any email with "<html>" in the message would get
+ tagged as being an html message. (Thanks to John Rouillard for that
+ bug report!)
+
+1.40 (Dec 04, 2002)
+ - A patch from Paul Kreiner (J.P van Oyen also reported a similar fix):
+ "This patch forces the timestamp string to always follow
+ the HH:MM:SS convention required by the RFCs, even if the
+ fields could be represented with a single digit. I also
+ took the liberty of adding a global "timezone" variable at
+ the top, and fixing a couple of typos."
+ - A patch from Reidar Johansen that included several fixes, but notably
+ he included a function called tz_offset that determines what timezone
+ your in.
+ - Fixed the signal handlers so they display a nice message
+ - Added a quit() function
+ - Added a printmsg() function to handle all printed/logged messages
+ - Added a simple openLogFile() function
+ - If running in Win32 it says "CTRL-Z" rather than "CTRL-D"
+ - Applied fix from Yakov Lerner to fix bare period encoding
+ - Check that attachments exist and are readable before trying to open them
+ - Rewrote the connect() function
+ - Rewrote the close/disconnect function
+ - Made the -v option work with any number of -v's
+ - Rewrote the read_server_response() function and renamed it to readServerResponse()
+ - Did a bunch of little fixes so that perl -w won't complain
+ - Redid the whole file logging stuff - now the printmsg function takes care of it,
+ and it's no longer partially broken.
+ - Added a global alarm variable for setting the alarm timeout, and changed
+ it's default value to 60 rather than 15.
+ - Fixed all the exit()'s so that sendEmail should now only exit with an
+ error status of 0 if it successfully sent the email.
+ - Added support for HTML email (Thanks again to Reidar Johansen)
+ - Re-worked the mime-encoding function to work with -w and use strict.
+ - Removed several die() calls in the file attachment process.
+ - Put a fix in place that should cleanly replace any bare LF's with CRLF.
+
+1.33 (Apr 16, 2001)
+ - Fixed some typo's and problems with the logging option regarding the
+ printing of attachment(s) names to the log file.
+ - Fixed several comparisons with null strings.
+ - Lots of little cleanup things.
+
+1.32 (Aug 18, 2000)
+ - Fixed a fairly serious error which in some circumstances would
+ cause file attachments to be corrupted because the mime padding at
+ the end of the attachment was not getting set correctly.
+
+1.31 (Aug 9, 2000)
+ - Totally rewrote all mime encoding code, it should now be 100%
+ MIME/Base64 compliant, and it now opens files in binary mode in win32.
+ This was a much bigger operation than it sounds like ;-)
+ - Now it should work with LARGE file attachments. In v1.30 it had to
+ load the whole file into memory before encoding it, now it encodes
+ line by line so it doesn't use nearly as much memory.
+ - Now checks the message for bare periods and encodes them.
+ - Fixed a bug that would allow text to be printed even if -q was
+ set (and -m was not).
+ - The MIME delimiter is now somewhat random.
+
+1.30 (Aug 1, 2000)
+ - ATTACHMENT SUPPORT ADDED!
+ - Added CC and BCC support, they are now normal command line options.
+ - sendEmail should now work easier in Win32. Win32 did not support
+ the alarm() calls, so I put a check that disables the alarm calls if
+ $^O matches 'Win'.
+ - Added autodetection of mime type on attachments.
+ - Disabled the alarm timer if there are attachments, that way people
+ on modems can send big attachments without getting their upload killed.
+ - Added a -q option for quiet mode
+ - Added a 'Date:' field in the mail headers so messages will
+ show up in the right order in my mail program ;-)
+ - Changed the way you specify a port form the command line
+ now you specify it in the -s <server> option as an
+ optional :port addendum to the server name.
+ - Added -h and --help support.
+ - Updated the help to reflect all changes.
+
+1.22 (Jul 8, 2000)
+ - Removed the 'content-type' and 'transfer encoding type' flags in the email
+ headers, in preparation for a version that will support real attachments.
+ - When piping data to sendEmail often email would have lines ending with
+ just \012 and many email servers do not like this. So I now have \012
+ replaced with \012\015 in data piped from STDIN.
+ - When piping data as the message it now displays a message for those manually
+ typing in an email. It also changes the 15 second alarm to a 60 second alarm
+ and resets it after every new line.
+
+1.21 (May 15, 2000)
+ - Removed the SIG_ALARM call (gave errors on certain non-slackware distributions)
+ - Added a missing error check that could have allowed sendEmail to say a
+ message was sent successfully when the server had actually returned an
+ error message.
+
+
+1.20 (May 10, 2000)
+ VERSION OVERVIEW:
+ -----------------
+ -v option added
+ -vv option added
+ Passing the body of the email via STDIN is now an option
+ Multiple <to> addresses now allowed
+ Logging feature added
+ Terminates itself after 15 seconds to avoid dns hangs etc
+ Lots of small potential bugs fixed and a lot of code cleanup
+
+ DETAILS:
+ --------
+ - DEBUG CODE/MODE:
+ - Lots of error messages everywhere
+ - 2 levels of verbosity accessible via command like parameters
+ - Lots more information messages triggered by $debug's value
+ - Fixed a problem which could have caused sendEmail to overlook certain
+ error messages from the email server.
+ - All invalid command line parameters are now reported correctly
+ - Some code comments were written incorrectly, and are now fixed.
+ - Added handler for HUP and ALARM (both kill sendEmail now)
+ - Possible problems with certain email addresses fixed.
+ - Modified date routine to not use a system call. (making it more portable)
+ - Improved command line parsing (preventing a few possible errors).
+ - Thanks to Nick Pasich for help with these patches:
+ - You can now send the body of the email via the -m option
+ as before or optionally leave the -m out and pass the body
+ of the email to STDIN.
+ - Alarm to abort sendEmail if it runs longer than 15 seconds
+ - Multiple 'To' addresses
+ - Option to log to a file
+ - Updated the 'help' page to reflect all changes
+
+
+1.01
+ - Fixed a bug in the error/success checking routine which caused sendEmail
+ to report errors when there were none.
+ Thanks to Michael Santy for this bug report.
+ - Added some more documentation in the code.
+ - Added this CHANGELOG file.
+ - Release v1.01

+GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or

+sendEmail - Send email from a console near you!
+Written by: Brandon Zehm <caspian@dotconf.net>
+http://caspian.dotconf.net/
+http://www.tsheets.com/
+
+
+
+------------------
+What is sendEmail?
+------------------
+
+SendEmail is a lightweight, completly command line based, SMTP email agent.
+If you have the need to send email from the command line, this tool is perfect.
+It was designed to be used in bash scripts, Perl programs, and web sites, but
+it is also quite useful in many other contexts. SendEmail is written in Perl
+and is unique in that it requires NO SPECIAL MODULES. It has an intuitive and
+flexible set of command-line options, making it very easy to learn and use.
+
+
+
+
+------------------
+Installation
+------------------
+
+SendEmail is a perl script/program, and only needs to be copied to a directory
+in your path to make it accessible. Most likely the following steps will
+be sufficient:
+
+1) Extract the package
+ tar -zxvf sendEmail-v1.XX.tar.gz
+
+2) Copy the sendEmail script to /usr/local/bin
+ cp -a sendEmail-v1.XX/sendEmail /usr/local/bin
+
+3) Make sure its executable
+ chmod +x /usr/local/bin/sendEmail
+
+4) Run it
+ sendEmail
+ or
+ /usr/local/bin/sendEmail
+
+NOTES:
+ * Running sendEmail without any arguments will produce a usage summary.
+ * SendEmail is written in Perl, so no compilation is needed.
+ * On a Unix/Linux OS if your perl binary is not installed at /usr/bin/perl
+ you may need to edit the first line of the script accordingly.
+
+
+
+
+
+

+Reported Bugs:
+ [ ] But it seems that I can't send more than 16 or 17 KB from the STDIN on Windows (2003) with the EXE version.
+ Even with -o message-file=... and got the same 17 KB message limitation.
+
+Feature Ideas
+ [ ] A preferences file with default settings?
+ [ ] Deliver directly to MX server for domain?
+ [ ] Command line option requesting read-receipt
+ X-Confirm-Reading-To:
+ Disposition-Notification-To: <user@domain.com>
+ Return-Receipt-To:
+ [ ] Add support for CRAM-MD5 authentication
+ [ ] Add a pair of options to add receipt on delivery and on read of sent emails
+ [ ] Support for unicode (european) characters in the subject
+
+More Ideas:
+ [ ] What about an option to send the same message more than once?
+ [ ] How about a delay before sending the message?
+ [ ] What about an internal queue for messages that wern't sent?
+ Next time it's invoked it could deliver those messages as well.
+ [ ] Convert inline documentation to standard perldoc format?
+ [ ] Support for pop before smtp?
+
+Crazy Ideas (not so sure about):
+ [ ] Preferences registry settings for the Windows .exe version?
+ (several people have said No! use a flat file)

+Options related to addressing:
+ -f ADDRESS

+ -bcc ADDRESS [ADDRESS ...]
+ -o reply-to=ADDRESS
+
+-f ADDRESS
+ This required option specifies who the email is from, I.E. the sender's
+ email address.
+
+-t ADDRESS [ADDRESS ...]
+ This option specifies the primary recipient(s). At least one recipient
+ address must be specified via the -t, -cc. or -bcc options.
+
+-cc ADDRESS [ADDRESS ...]
+ This option specifies the "carbon copy" recipient(s). At least one
+ recipient address must be specified via the -t, -cc. or -bcc options.
+
+-bcc ADDRESS [ADDRESS ...]
+ This option specifies the "blind carbon copy" recipient(s). At least
+ one recipient address must be specified via the -t, -cc. or -bcc options.
+
+-o reply-to=ADDRESS
+ This option specifies that an optional "Reply-To" address should be
+ written in the email's headers.
+
+
+${colorGreen}Email Address Syntax${colorNormal}
+Email addresses may be specified in one of two ways:
+ Full Name: "John Doe <john.doe\@gmail.com>"
+ Just Address: "john.doe\@gmail.com"
+
+The "Full Name" method is useful if you want a name, rather than a plain
+email address, to be displayed in the recipient's From, To, or Cc fields
+when they view the message.
+
+
+${colorGreen}Multiple Recipients${colorNormal}
+The -t, -cc, and -bcc options each accept multiple addresses. They may be
+specified by separating them by either a white space, comma, or semi-colon
+separated list. You may also specify the -t, -cc, and -bcc options multiple
+times, each occurance will append the new recipients to the respective list.
+
+Examples:
+(I used "-t" in these examples, but it can be "-cc" or "-bcc" as well)
+
+ * Space separated list:
+ -t jane.doe\@yahoo.com "John Doe <john.doe\@gmail.com>"
+
+ * Semi-colon separated list:
+ -t "jane.doe\@yahoo.com; John Doe <john.doe\@gmail.com>"
+
+ * Comma separated list:
+ -t "jane.doe\@yahoo.com, John Doe <john.doe\@gmail.com>"

+${colorGreen}Message Options${colorNormal}
+Options related to the email message body:
+ -u SUBJECT
+ -m MESSAGE
+ -o message-file=FILE
+ -o message-content-type=<auto|text|html>
+ -o message-header=EMAIL HEADER
+ -o message-charset=CHARSET
+ -o message-format=raw
+
+-u SUBJECT
+ This option allows you to specify the subject for your email message.
+ It is not required (anymore) that the subject be quoted, although it
+ is recommended. The subject will be read until an argument starting
+ with a hyphen (-) is found.
+ Examples:
+ -u "Contact information while on vacation"
+ -u New Microsoft vulnerability discovered
+
+-m MESSAGE
+ This option is one of three methods that allow you to specify the message
+ body for your email. The message may be specified on the command line
+ with this -m option, read from a file with the -o message-file=FILE
+ option, or read from STDIN if neither of these options are present.
+
+ It is not required (anymore) that the message be quoted, although it is
+ recommended. The message will be read until an argument starting with a
+ hyphen (-) is found.
+ Examples:
+ -m "See you in South Beach, Hawaii. -Todd"
+ -m Please ensure that you upgrade your systems right away
+
+ Multi-line message bodies may be specified with the -m option by putting
+ a "\\n" into the message. Example:
+ -m "This is line 1.\\nAnd this is line 2."
+
+ HTML messages are supported, simply begin your message with "<html>" and
+ sendEmail will properly label the mime header so MUAs properly render
+ the message. It is currently not possible without "-o message-format=raw"
+ to send a message with both text and html parts with sendEmail.
+
+-o message-file=FILE
+ This option is one of three methods that allow you to specify the message
+ body for your email. To use this option simply specify a text file
+ containing the body of your email message. Examples:
+ -o message-file=/root/message.txt
+ -o message-file="C:\\Program Files\\output.txt"
+
+-o message-content-type=<auto|text|html>
+ This option allows you to specify the content-type of the email. If your
+ email message is an html message but is being displayed as a text message
+ just add "-o message-content-type=html" to the command line to force it
+ to display as an html message. This actually just changes the Content-Type:
+ header. Advanced users will be happy to know that if you specify anything
+ other than the three options listed above it will use that as the vaule
+ for the Content-Type header.
+
+-o message-header=EMAIL HEADER
+ This option allows you to specify additional email headers to be included.
+ To add more than one message header simply use this option on the command
+ line more than once. If you specify a message header that sendEmail would
+ normally generate the one you specified will be used in it's place.
+ Do not use this unless you know what you are doing!
+ Example:
+ To scare a Microsoft Outlook user you may want to try this:
+ -o message-header="X-Message-Flag: Message contains illegal content"
+ Example:
+ To request a read-receipt try this:
+ -o message-header="Disposition-Notification-To: <user\@domain.com>"
+ Example:
+ To set the message priority try this:
+ -o message-header="X-Priority: 1"
+ Priority reference: 1=highest, 2=high, 3=normal, 4=low, 5=lowest
+
+-o message-charset=CHARSET
+ This option allows you to specify the character-set for the message body.
+ The default is iso-8859-1.
+
+-o message-format=raw
+ This option instructs sendEmail to assume the message (specified with -m,
+ read from STDIN, or read from the file specified in -o message-file=FILE)
+ is already a *complete* email message. SendEmail will not generate any
+ headers and will transmit the message as-is to the remote SMTP server.
+ Due to the nature of this option the following command line options will
+ be ignored when this one is used:
+ -u SUBJECT
+ -o message-header=EMAIL HEADER
+ -o message-charset=CHARSET
+ -a ATTACHMENT
+
+
+${colorGreen}The Message Body${colorNormal}
+The email message body may be specified in one of three ways:
+ 1) Via the -m MESSAGE command line option.
+ Example:
+ -m "This is the message body"
+
+ 2) By putting the message body in a file and using the -o message-file=FILE
+ command line option.
+ Example:
+ -o message-file=/root/message.txt
+
+ 3) By piping the message body to sendEmail when nither of the above command
+ line options were specified.
+ Example:
+ grep "ERROR" /var/log/messages | sendEmail -t you\@domain.com ...
+
+If the message body begins with "<html>" then the message will be treated as
+an HTML message and the MIME headers will be written so that a HTML capable
+email client will display the message in it's HTML form.
+Any of the above methods may be used with the -o message-format=raw option
+to deliver an already complete email message.

+ -o username=USERNAME
+ -o password=PASSWORD
+ -o tls=<auto|yes|no>
+ -o timeout=SECONDS
+ -o fqdn=FQDN
+
+-a ATTACHMENT [ATTACHMENT ...]
+ This option allows you to attach any number of files to your email message.
+ To specify more than one attachment, simply separate each filename with a
+ space. Example: -a file1.txt file2.txt file3.txt
+
+-xu USERNAME
+ Alias for -o username=USERNAME
+
+-xp PASSWORD
+ Alias for -o password=PASSWORD
+
+-o username=USERNAME (synonym for -xu)
+ These options allow specification of a username to be used with SMTP
+ servers that require authentication. If a username is specified but a
+ password is not, you will be prompted to enter one at runtime.
+
+-o password=PASSWORD (synonym for -xp)
+ These options allow specification of a password to be used with SMTP
+ servers that require authentication. If a username is specified but a
+ password is not, you will be prompted to enter one at runtime.
+
+-o tls=<auto|yes|no>
+ This option allows you to specify if TLS (SSL for SMTP) should be enabled
+ or disabled. The default, auto, will use TLS automatically if your perl
+ installation has the IO::Socket::SSL and Net::SSLeay modules available,
+ and if the remote SMTP server supports TLS. To require TLS for message
+ delivery set this to yes. To disable TLS support set this to no. A debug
+ level of one or higher will reveal details about the status of TLS.
+
+-o timeout=SECONDS
+ This option sets the timeout value in seconds used for all network reads,
+ writes, and a few other things.
+
+-o fqdn=FQDN
+ This option sets the Fully Qualified Domain Name used during the initial
+ SMTP greeting. Normally this is automatically detected, but in case you
+ need to manually set it for some reason or get a warning about detection
+ failing, you can use this to override the default.

+Options related to networking:
+ -s SERVER[:PORT]
+ -b BINDADDR[:PORT]
+ -o tls=<auto|yes|no>
+ -o timeout=SECONDS
+
+-s SERVER[:PORT]
+ This option allows you to specify the SMTP server sendEmail should
+ connect to to deliver your email message to. If this option is not
+ specified sendEmail will try to connect to localhost:25 to deliver
+ the message. THIS IS MOST LIKELY NOT WHAT YOU WANT, AND WILL LIKELY
+ FAIL unless you have a email server (commonly known as an MTA) running
+ on your computer!
+ Typically you will need to specify your company or ISP's email server.
+ For example, if you use CableOne you will need to specify:
+ -s mail.cableone.net
+ If you have your own email server running on port 300 you would
+ probably use an option like this:
+ -s myserver.mydomain.com:300
+ If you're a GMail user try:
+ -s smtp.gmail.com:587 -xu me\@gmail.com -xp PASSWD
+
+-b BINDADDR[:PORT]
+ This option allows you to specify the local IP address (and optional
+ tcp port number) for sendEmail to bind to when connecting to the remote
+ SMTP server. This useful for people who need to send an email from a
+ specific network interface or source address and are running sendEmail on
+ a firewall or other host with several network interfaces.
+
+-o tls=<auto|yes|no>
+ This option allows you to specify if TLS (SSL for SMTP) should be enabled
+ or disabled. The default, auto, will use TLS automatically if your perl
+ installation has the IO::Socket::SSL and Net::SSLeay modules available,
+ and if the remote SMTP server supports TLS. To require TLS for message
+ delivery set this to yes. To disable TLS support set this to no. A debug

+
+-l LOGFILE
+ This option allows you to specify a log file to append to. Every message
+ that is displayed to STDOUT is also written to the log file. This may be
+ used in conjunction with -q and -v.
+
+-q
+ This option tells sendEmail to disable printing to STDOUT. In other
+ words nothing will be printed to the console. This does not affect the
+ behavior of the -l or -v options.
+
+-v
+ This option allows you to increase the debug level of sendEmail. You may
+ either use this option more than once, or specify more than one v at a
+ time to obtain a debug level higher than one. Examples:
+ Specifies a debug level of 1: -v
+ Specifies a debug level of 2: -vv
+ Specifies a debug level of 2: -v -v
+ A debug level of one is recommended when doing any sort of debugging.
+ At that level you will see the entire SMTP transaction (except the
+ body of the email message), and hints will be displayed for most
+ warnings and errors. The highest debug level is three.
