NAME

Mail::Transport::Send - send a message

INHERITANCE

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

 Mail::Transport::Send is extended by
   Mail::Transport::Exim
   Mail::Transport::Mailx
   Mail::Transport::Qmail
   Mail::Transport::SMTP
   Mail::Transport::Sendmail

SYNOPSIS

 my $message = Mail::Message->new(...);

 # Some extensions implement sending:
 $message->send;
 $message->send(via => 'sendmail');

 my $sender = Mail::Transport::SMTP->new(...);
 $sender->send($message);

DESCRIPTION

Send a message to the destinations as specified in the header. The "Mail::Transport::Send" module is capable of autodetecting which of the following modules work on your system; you may simply call "send" without "via" options to get a message transported.

•: Mail::Transport::Sendmail
Use sendmail to process and deliver the mail. This requires the "sendmail" program to be installed on your system. Whether this is an original sendmail, or a replacement from Postfix does matter.
•: Mail::Transport::Exim
Use "exim" to distribute the message.
•: Mail::Transport::Qmail
Use "qmail-inject" to distribute the message.
•: Mail::Transport::SMTP
In this case, Perl is handling mail transport on its own. This is less desired but more portable than sending with sendmail or qmail. The advantage is that this sender is environment independent, and easier to configure. However, there is no daemon involved which means that your program will wait until the message is delivered, and the message is lost when your program is interrupted during delivery (which may take hours to complete).
•: Mail::Transport::Mailx
Use the external "mail", "mailx", or "Mail" programs to send the message. Usually, the result is poor, because some versions of these programs do not support MIME headers. Besides, these programs are known to have exploitable security breaches.

Sending mail

$obj->destinations( $message, [$address|ARRAY] )

Determine the destination for this message. If a valid $address is defined, this is used to overrule the addresses within the message. If the $address is "undef" it is ignored. It may also be an ARRAY of addresses.

If no $address is specified, the message is scanned for resent groups (see Mail::Message::Head::Complete::resentGroups()). The addresses found in the first (is latest added) group are used. If no resent groups are found, the normal "To", "Cc", and "Bcc" lines are taken.

$obj->putContent($message, $fh, %options)

Print the content of the $message to the $fh.

 -Option     --Default
  body_only    <false>
  undisclosed  <false>

body_only => BOOLEAN: Print only the body of the message, not the whole.
undisclosed => BOOLEAN: Do not print the "Bcc" and "Resent-Bcc" lines. Default false, which means that they are not printed.

$obj->send($message, %options)

Transmit the $message, which may be anything what can be coerced into a Mail::Message, so including Mail::Internet and MIME::Entity messages. It returns true when the transmission was successfully completed.

 -Option  --Default
  interval  new(interval)
  retry     new(retry)
  to        undef

interval => SECONDS
retry => INTEGER
to => STRING: Overrules the destination(s) of the message, which is by default taken from the (Resent-)To, (Resent-)Cc, and (Resent-)Bcc.

$obj->trySend($message, %options)

Try to send the message. This will return true if successful, and false in case some problems where detected. The $? contains the exit status of the command which was started.

DIAGNOSTICS

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.

Error: Transporters of type $class cannot send.

The Mail::Transport object of the specified type can not send messages, but only receive message.
