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.
