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.

       See documentation in the base class.

             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.
