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.
Extends "DESCRIPTION" in Mail::Transport::Send.

via Mail::Transport 'smtp'
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] )

$obj->tryConnectTo($host, %options)

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.
