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.

METHODS

Constructors

Mail::Transport::SMTP->new(OPTIONS)

 Option      Defined in       Default           
 executable  L<Mail::Transport>  C<undef>          
 helo                         <from Net::Config>
 hostname    L<Mail::Transport>  <from Net::Config>

 username                     undef             
 via         L<Mail::Transport>  C<'smtp'>

. 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 the Mail::Transport::Send manpage

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

See Sending mail in the Mail::Transport::Send manpage

$obj->send(MESSAGE, OPTIONS)

See Sending mail in the Mail::Transport::Send manpage

$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  Defined in       Default    
 from                     E<lt> E<gt>
 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 the Mail::Transport manpage

$obj->remoteHost

See Server connection in the Mail::Transport manpage

$obj->retry

See Server connection in the Mail::Transport manpage

$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.

Error handling

$obj->AUTOLOAD

See Error handling in the Mail::Reporter manpage

$obj->addReport(OBJECT)

See Error handling in the Mail::Reporter manpage

$obj->defaultTrace([LEVEL]|[LOGLEVEL, TRACELEVEL]|[LEVEL, CALLBACK])

Mail::Transport::SMTP->defaultTrace([LEVEL]|[LOGLEVEL, TRACELEVEL]|[LEVEL, CALLBACK])

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.
