NAME

       Mail::Transport::Sendmail - transmit messages using external Sendmail program

INHERITANCE

        Mail::Transport::Sendmail
          is a Mail::Transport::Send
          is a Mail::Transport
          is a Mail::Reporter

SYNOPSIS

        my $sender = Mail::Transport::Sendmail->new(...);
        $sender->send($message);

DESCRIPTION

       Implements mail transport using the external 'Sendmail' program.  When instantiated, the mailer will look
       for the binary in specific system directories, and the first version found is taken.

       Some people use Postfix as MTA.  Postfix can be installed as replacement for Sendmail: is provides a
       program with the same name and options.  So, this module supports postfix as well.

       WARNING: When you do bulk email sending with local delivery via Postfix, you can probably better use the
       SMTP backend to connect to postfix.  The "sendmail" command delivers to "maildrop".  From "maildrop", the
       "pickupd" will only sequentially insert messages into "cleanup".  That process can take considerable
       elapse time.  Directly inserting via "smtpd" will parallellize the cleanup process.

             Add  to  the  command-line  of the started sendmail MTU a list of separate words.  So say " [ '-f',
             $file ] " and not " [ "-f $file" ] ", because the latter will be taken  by  sendmail  as  one  word
             only.

DIAGNOSTICS

       Error: Errors when closing sendmail mailer $program: $!
           The  was  no  problem  starting  the  sendmail  mail transfer agent, but for some specific reason the
           message could not be handled correctly.

       Warning: Message has no destination
           It was not possible to figure-out where the message is intended to go to.

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does not implement this  method  where
           it  should.  This  message means that some other related classes do implement this method however the
           class at hand does not.  Probably you should investigate this and probably inform the author  of  the
           package.

       Warning: Resent group does not specify a destination
           The   message   which   is   sent   is   the   result   of   a  bounce  (for  instance  created  with
           Mail::Message::bounce()), and therefore starts with a "Received" header field.   With  the  "bounce",
           the  new  destination(s)  of  the  message  are  given,  which  should  be  included  as "Resent-To",
           "Resent-Cc", and "Resent-Bcc".

           The "To", "Cc", and "Bcc" header information is only used if no "Received" was found.  That seems  to
           be the best explanation of the RFC.

           As  alternative,  you  may  also  specify  the  "to"  option  to  some  of  the senders (for instance
           Mail::Transport::SMTP::send(to) to overrule any information found in the  message  itself  about  the
           destination.
