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.
