       Mail::Sendmail - Simple platform independent mailer

         use Mail::Sendmail;

         %mail = ( To      => 'you AT there.com',
                   From    => 'me AT here.com',
                   Message => "This is a very short message"

         sendmail(%mail) or die $Mail::Sendmail::error;

         print "OK. Log says:\n", $Mail::Sendmail::log;

       Simple platform independent e-mail from your perl script. Only requires Perl 5 and a
       network connection.

       Mail::Sendmail takes a hash with the message to send and sends it to your mail server. It
       is intended to be very easy to setup and use. See also "FEATURES" below, and as usual,
       read this documentation.

       There is also a FAQ (see "NOTES").

           "perl -MCPAN -e "install Mail::Sendmail""

               perl Makefile.PL
               make test
               make install

           Copy Sendmail.pm to Mail/ in your Perl lib directory.

               (eg. c:\Perl\site\lib\Mail\
                or  /usr/lib/perl5/site_perl/Mail/
                or whatever it is on your system.
                They are listed when you type C< perl -V >)

       ActivePerl's PPM
           Depending on your PPM version:

               ppm install --location=http://alma.ch/perl/ppm Mail-Sendmail


               ppm install http://alma.ch/perl/ppm/Mail-Sendmail.ppd

           But this way you don't get a chance to have a look at other files (Changes, Todo,
           test.pl, ...).

       At the top of Sendmail.pm, set your default SMTP server(s), unless you specify it with
       each message, or want to use the default (localhost).

       Install MIME::QuotedPrint. This is not required but strongly recommended.

       Automatic time zone detection, Date: header, MIME quoted-printable encoding (if
       MIME::QuotedPrint installed), all of which can be overridden.

       Bcc: and Cc: support.

       Allows real names in From:, To: and Cc: fields

       Doesn't send an X-Mailer: header (unless you do), and allows you to send any header(s) you

       Configurable retries and use of alternate servers if your mail server is down

       Good plain text error reporting

       Experimental support for SMTP AUTHentication

       Headers are not encoded, even if they have accented characters.

       Since the whole message is in memory, it's not suitable for sending very big attached

       The SMTP server has to be set manually in Sendmail.pm or in your script, unless you have a
       mail server on localhost.

       Doesn't work on OpenVMS, I was told. Cannot test this myself.

       Default SMTP server(s)
           This is probably all you want to configure. It is usually done through $mailcfg{smtp},
           which you can edit at the top of the Sendmail.pm file.  This is a reference to a list
           of SMTP servers. You can also set it from your script:

           "unshift @{$Mail::Sendmail::mailcfg{'smtp'}} , 'my.mail.server';"

           Alternatively, you can specify the server in the %mail hash you send from your script,
           which will do the same thing:

           "$mail{smtp} = 'my.mail.server';"

           A future version will (hopefully) try to set useful defaults for you during the

       Other configuration settings
           See %mailcfg under "DETAILS" below for other configuration options.


       sendmail is the only thing exported to your namespace by default

       "sendmail(%mail) || print "Error sending mail: $Mail::Sendmail::error\n";"

       It takes a hash containing the full message, with keys for all headers and the body, as
       well as for some specific options.

       It returns 1 on success or 0 on error, and rewrites $Mail::Sendmail::error and

       Keys are NOT case-sensitive.

       The colon after headers is not necessary.

       The Body part key can be called 'Body', 'Message' or 'Text'.

       The SMTP server key can be called 'Smtp' or 'Server'. If the connection to this one fails,
       the other ones in $mailcfg{smtp} will still be tried.

       The following headers are added unless you specify them yourself:

           Mime-Version: 1.0
           Content-Type: 'text/plain; charset="iso-8859-1"'

           Content-Transfer-Encoding: quoted-printable
           or (if MIME::QuotedPrint not installed)
           Content-Transfer-Encoding: 8bit

           Date: [string returned by time_to_date()]

       If you wish to use an envelope sender address different than the From: address, set
       $mail{Sender} in your %mail hash.

       The following are not exported by default, but you can still access them with their full
       name, or request their export on the use line like in: "use Mail::Sendmail qw(sendmail
       $address_rx time_to_date);"

       embedding options in your %mail hash

       The following options can be set in your %mail hash. The corresponding keys will be
       removed before sending the mail.

       $mail{smtp} or $mail{server}
           The SMTP server to try first. It will be added

           This option will be removed. To use a non-standard port, set it in your server name:

           $mail{server}='my.smtp.server:2525' will try to connect to port 2525 on server

           This must be a reference to a hash containg all your authentication options:

           $mail{auth} = \%options; or $mail{auth} = {user=>"username", password=>"password",
           method=>"DIGEST-MD5", required=>0 };


           pass or password

               optional method. compared (stripped down) to available methods. If empty, will try
               all available.

               optional. defaults to false. If set to true, no delivery will be attempted if
               authentication fails. If false or undefined, and authentication fails or is not
               available, sending is tried without.

               (different auth for different servers?)


       convert time ( as from "time()" ) to an RFC 822 compliant string for the Date header. See
       also "%Mail::Sendmail::mailcfg".


       When you don't run with the -w flag, the module sends no errors to STDERR, but puts
       anything it has to complain about in here. You should probably always check if it says


       A summary that you could write to a log file after each send


       A handy regex to recognize e-mail addresses.

       A correct regex for valid e-mail addresses was written by one of the judges in the
       obfuscated Perl contest... :-) It is quite big. This one is an attempt to a reasonable
       compromise, and should accept all real-world internet style addresses. The domain part is
       required and comments or characters that would need to be quoted are not supported.

           $rx = $Mail::Sendmail::address_rx;
           if (/$rx/) {


       This hash contains installation-wide configuration options. You normally edit it once (if
       ever) in Sendmail.pm and forget about it, but you could also access it from your scripts.
       For readability, I'll assume you have imported it (with something like "use Mail::Sendmail
       qw(sendmail %mailcfg)").

       The keys are not case-sensitive: they are all converted to lowercase before use. Writing
       "$mailcfg{Port} = 2525;" is OK: the default $mailcfg{port} (25) will be deleted and
       replaced with your new value of 2525.

           "$mailcfg{smtp} = [qw(localhost my.other.mail.server)];"

           This is a reference to a list of smtp servers, so if your main server is down, the
           module tries the next one. If one of your servers uses a special port, add it to the
           server name with a colon in front, to override the default port (like in

           Default: localhost.

           "$mailcfg{from} = 'Mailing script me AT mydomain.com';"

           From address used if you don't supply one in your script. Should not be of type
           'user@localhost' since that may not be valid on the recipient's host.

           Default: undefined.

           "$mailcfg{mime} = 1;"

           Set this to 0 if you don't want any automatic MIME encoding. You normally don't need
           this, the module should 'Do the right thing' anyway.

           Default: 1;

           "$mailcfg{retries} = 1;"

           How many times should the connection to the same SMTP server be retried in case of a

           Default: 1;

           "$mailcfg{delay} = 1;"

           Number of seconds to wait between retries. This delay also happens before trying the
           next server in the list, if the retries for the current server have been exhausted.
           For CGI scripts, you want few retries and short delays to return with a results page
           before the http connection times out. For unattended scripts, you may want to use many
           retries and long delays to have a good chance of your mail being sent even with
           temporary failures on your network.

           Default: 1 (second);

           "$mailcfg{tz} = '+0800';"

           Normally, your time zone is set automatically, from the difference between "time()"
           and "gmtime()". This allows you to override automatic detection in cases where your
           system is confused (such as some Win32 systems in zones which do not use daylight
           savings time: see Microsoft KB article Q148681)

           Default: undefined (automatic detection at run-time).

           "$mailcfg{port} = 25;"

           Port used when none is specified in the server name.

           Default: 25.

           "$mailcfg{debug} = 0;"

           Prints stuff to STDERR. Current maximum is 6, which prints the whole SMTP session,
           except data exceeding 500 bytes.

           Default: 0;

       Configuration variables from previous versions

       The following global variables were used in version 0.74 for configuration.  As from
       version 0.78_1, they are not supported anymore.  Use the %mailcfg hash if you need to
       access the configuration from your scripts.


         use Mail::Sendmail;

         print "Testing Mail::Sendmail version $Mail::Sendmail::VERSION\n";
         print "Default server: $Mail::Sendmail::mailcfg{smtp}->[0]\n";
         print "Default sender: $Mail::Sendmail::mailcfg{from}\n";

         %mail = (
             #To      => 'No to field this time, only Bcc and Cc',
             #From    => 'not needed, use default',
             Bcc     => 'Someone <him AT there.com>, Someone else her AT there.com',
             # only addresses are extracted from Bcc, real names disregarded
             Cc      => 'Yet someone else <xz AT whatever.com>',
             # Cc will appear in the header. (Bcc will not)
             Subject => 'Test message',
             'X-Mailer' => "Mail::Sendmail version $Mail::Sendmail::VERSION",

         $mail{Smtp} = 'special_server.for-this-message-only.domain.com';
         $mail{'X-custom'} = 'My custom additionnal header';
         $mail{'mESSaGE : '} = "The message key looks terrible, but works.";
         # cheat on the date:
         $mail{Date} = Mail::Sendmail::time_to_date( time() - 86400 );

         if (sendmail %mail) { print "Mail sent OK.\n" }
         else { print "Error sending mail: $Mail::Sendmail::error \n" }

         print "\n\$Mail::Sendmail::log says:\n", $Mail::Sendmail::log;

       Main changes since version 0.79:

       Experimental SMTP AUTH support (LOGIN PLAIN CRAM-MD5 DIGEST-MD5)

       Fix bug where one refused RCPT TO: would abort everything

       send EHLO, and parse response

       Better handling of multi-line responses, and better error-messages

       Non-conforming line-endings also normalized in headers

       Now keeps the Sender header if it was used. Previous versions only used it for the MAIL
       FROM: command and deleted it.

       See the Changes file for the full history. If you don't have it because you installed
       through PPM, you can also find the latest one on

       On Debian systems Sys::Hostname::Long is tried before Sys::Hostname in order get a fully
       qualified domain name.

       Milivoj Ivkovic <mi\x40alma.ch> ("\x40" is "@" of course)

       MIME::QuotedPrint is used by default on every message if available. It allows reliable
       sending of accented characters, and also takes care of too long lines (which can happen in
       HTML mails). It is available in the MIME-Base64 package at
       http://www.perl.com/CPAN/modules/by-module/MIME/ or through PPM.

       Look at http://alma.ch/perl/Mail-Sendmail-FAQ.html for additional info (CGI, examples of
       sending attachments, HTML mail etc...)

       You can use this module freely. (Someone complained this is too vague.  So, more
       precisely: do whatever you want with it, but be warned that terrible things will happen to
       you if you use it badly, like for sending spam, or ...?)

       Thanks to the many users who sent me feedback, bug reports, suggestions, etc.  And please
       excuse me if I forgot to answer your mail. I am not always reliabe in answering mail. I
       intend to set up a mailing list soon.
