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


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


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


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.

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.

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.
