7       program
8

INHERITANCE

10        Mail::Transport::Sendmail
11          is a Mail::Transport::Send
12          is a Mail::Transport
13          is a Mail::Reporter
14

SYNOPSIS

16        my $sender = Mail::Transport::Sendmail->new(...);
17        $sender->send($message);
18

DESCRIPTION

20       Implements mail transport using the external 'Sendmail' program.  When
21       instantiated, the mailer will look for the binary in specific system
22       directories, and the first version found is taken.
23
24       Some people use Postfix as MTA.  Postfix can be installed as
25       replacement for Sendmail: is provides a program with the same name and
26       options.  So, this module supports postfix as well.
27
28       WARNING: When you do bulk email sending with local delivery via
29       Postfix, you can probably better use the SMTP backend to connect to
30       postfix.  The "sendmail" command delivers to "maildrop".  From
31       "maildrop", the "pickupd" will only sequentially insert messages into
32       "cleanup".  That process can take considerable elapse time.  Directly
33       inserting via "smtpd" will parallellize the cleanup process.

68             Add to the command-line of the started sendmail MTU a list of

70             $file" ] ", because the latter will be taken by sendmail as one
71             word only.

DIAGNOSTICS

159       Error: Errors when closing sendmail mailer $program: $!
160           The was no problem starting the sendmail mail transfer agent, but
161           for some specific reason the message could not be handled
162           correctly.
163
164       Warning: Message has no destination
165           It was not possible to figure-out where the message is intended to
166           go to.
167
168       Error: Package $package does not implement $method.
169           Fatal error: the specific package (or one of its superclasses) does
170           not implement this method where it should. This message means that
171           some other related classes do implement this method however the
172           class at hand does not.  Probably you should investigate this and
173           probably inform the author of the package.
174
175       Warning: Resent group does not specify a destination
176           The message which is sent is the result of a bounce (for instance
177           created with Mail::Message::bounce()), and therefore starts with a
178           "Received" header field.  With the "bounce", the new destination(s)
179           of the message are given, which should be included as "Resent-To",
180           "Resent-Cc", and "Resent-Bcc".
181
182           The "To", "Cc", and "Bcc" header information is only used if no
183           "Received" was found.  That seems to be the best explanation of the
184           RFC.
185
186           As alternative, you may also specify the "to" option to some of the
187           senders (for instance Mail::Transport::SMTP::send(to) to overrule
188           any information found in the message itself about the destination.
