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.

warning: you may need to install Net::SMTPS, to get TLS support.

esmtp_options => HASH: [2.116] ESMTP options to pass to Net::SMTP. See the Net::SMTP documentation for full details. Options can also be passed at send time. For example: { XVERP => 1 }
executable => FILENAME
from => ADDRESS: Allows a default sender address to be specified globally. See trySend() for full details.
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
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

Extends "Sending mail" in Mail::Transport::Send.

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

Inherited, see "Sending mail" in Mail::Transport::Send

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

Inherited, see "Sending mail" in Mail::Transport::Send

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

Inherited, 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 six values:

(success, rc, rc-text, error location, quit success, accept)

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

[3.003] the 'accept' returns the message of the dataend() instruction. Some servers may provide useful information in there, like an internal message registration id. For example, postfix may return "2.0.0 Ok: queued as 303EA380EE". You can only use this parameter when running local delivery (which is a smart choice anyway)

-Option       --Default
 esmtp_options  {}
 from           < >
 to             []

esmtp_options => HASH: Additional or overridden EMSTP options. See new(esmtp_options)
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

Extends "Server connection" in Mail::Transport::Send.

$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] ): Inherited, see "Server connection" in Mail::Transport
$obj->remoteHost(): Inherited, see "Server connection" in Mail::Transport
$obj->retry(): Inherited, 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.

Error handling

Extends "Error handling" in Mail::Transport::Send.

$obj->AUTOLOAD(): Inherited, see "Error handling" in Mail::Reporter
$obj->addReport($object): Inherited, see "Error handling" in Mail::Reporter
$obj->defaultTrace( [$level]|[$loglevel, $tracelevel]|[$level, $callback] )
Mail::Transport::SMTP->defaultTrace( [$level]|[$loglevel, $tracelevel]|[$level, $callback] ): Inherited, see "Error handling" in Mail::Reporter
$obj->errors(): Inherited, see "Error handling" in Mail::Reporter
$obj->log( [$level, [$strings]] )
Mail::Transport::SMTP->log( [$level, [$strings]] ): Inherited, see "Error handling" in Mail::Reporter
$obj->logPriority($level)
Mail::Transport::SMTP->logPriority($level): Inherited, see "Error handling" in Mail::Reporter
$obj->logSettings(): Inherited, see "Error handling" in Mail::Reporter
$obj->notImplemented(): Inherited, see "Error handling" in Mail::Reporter
$obj->report( [$level] ): Inherited, see "Error handling" in Mail::Reporter
$obj->reportAll( [$level] ): Inherited, see "Error handling" in Mail::Reporter
$obj->trace( [$level] ): Inherited, see "Error handling" in Mail::Reporter
$obj->warnings(): Inherited, see "Error handling" in Mail::Reporter

Cleanup

$obj->DESTROY(): Inherited, see "Cleanup" in Mail::Reporter

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.
