Mail::Transport::SMTP.3pm

NAME

Mail::Transport::SMTP - transmit messages without external program

INHERITANCE

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

SYNOPSIS

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

DESCRIPTION

This module implements transport of "Mail::Message" objects by negotiating to the destination host directly by using the SMTP protocol, without help of "sendmail", "mail", or other programs on the local host.

. executable => FILENAME
. helo => HOST

The fully qualified name of the sender's host (your system) which is used for the greeting message to the receiver. If not specified, Net::Config or else Net::Domain are questioned to find it. When even these do not supply a valid name, the name of the domain in the "From" line of the message is assumed.

. hostname => HOSTNAME|ARRAY-OF-HOSTNAMES
. interval => SECONDS
. log => LEVEL
. password => STRING

The password to be used with the new(username) to log in to the remote server.

. port => INTEGER
. proxy => PATH
. retry => NUMBER|undef
. smtp_debug => BOOLEAN

Simulate transmission: the SMTP protocol output will be sent to your screen.

. timeout => SECONDS

The number of seconds to wait for a valid response from the server before failing.

. trace => LEVEL
. username => STRING

Use SASL authentication to contact the remote SMTP server (RFC2554). This username in combination with new(password) is passed as arguments to Net::SMTP method auth. Other forms of authentication are not supported by Net::SMTP. The "username" can also be specified as an Authen::SASL object.

. via => CLASS|NAME

Sending mail

$obj->destinations(MESSAGE, [ADDRESS|ARRAY-OF-ADDRESSES])

See ``Sending mail'' in Mail::Transport::Send

$obj->putContent(MESSAGE, FILEHANDLE, OPTIONS)

See ``Sending mail'' in Mail::Transport::Send

$obj->send(MESSAGE, OPTIONS)

See ``Sending mail'' in Mail::Transport::Send

$obj->trySend(MESSAGE, OPTIONS)

Try to send the MESSAGE once. This may fail, in which case this method will return "false". In list context, the reason for failure can be caught: in list context "trySend" will return a list of five values:

  (success, error code, error text, error location, quit success)
 
 

Success and quit success are booleans. The error code and -text are protocol specific codes and texts. The location tells where the problem occurred.

  Option--Default
  from    < >
  to      []
 
 

. from => ADDRESS

Your own identification. This may be fake. If not specified, it is taken from Mail::Message::sender(), which means the content of the "Sender" field of the message or the first address of the "From" field. This defaults to ``< >'', which represents ``no address''.

. to => ADDRESS|[ADDRESSES]

Alternative destinations. If not specified, the "To", "Cc" and "Bcc" fields of the header are used. An address is a string or a Mail::Address object.

Server connection

$obj->contactAnyServer

Creates the connection to the SMTP server. When more than one hostname was specified, the first which accepts a connection is taken. An IO::Socket::INET object is returned.

$obj->findBinary(NAME [, DIRECTORIES])

See ``Server connection'' in Mail::Transport

$obj->remoteHost

See ``Server connection'' in Mail::Transport

$obj->retry

See ``Server connection'' in Mail::Transport

$obj->tryConnectTo(HOST, OPTIONS)

Try to establish a connection to deliver SMTP to the specified HOST. The OPTIONS are passed to the "new" method of Net::SMTP.

DIAGNOSTICS

Warning: Message has no destination

It was not possible to figure-out where the message is intended to go to.

Notice: No addresses found to send the message to, no connection made

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.
