NAME

Mail::Transport - use Mail Transfer Agents (MTAs)

INHERITANCE

Mail::Transport
  is a Mail::Reporter

Mail::Transport is extended by
  Mail::Transport::Receive
  Mail::Transport::Send

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);

# Some extensions implement receiving:
my $receiver = Mail::Transport::POP3->new(...);
$message = $receiver->receive;

DESCRIPTION

Objects which extend Mail::Transport implement sending and/or receiving of messages, using various protocols.

Mail::Transport::Send extends this class, and offers general functionality for send protocols, like SMTP. Mail::Transport::Receive also extends this class, and offers receive method. Some transport protocols will implement both sending and receiving.

executable => FILENAME

If you specify an executable, the module does not need to search the system directories to figure-out where the client lives. Using this decreases the flexible usage of your program: moving your program to other systems may involve changing the path to the executable, which otherwise would work auto-detect and unmodified.

hostname => HOSTNAME|ARRAY

The host on which the server runs. Some protocols accept an ARRAY of alternatives for this option.

interval => SECONDS

The time between tries to contact the remote server for sending or receiving a message in SECONDS. This number must be larger than 0.

log => LEVEL

password => STRING

Some protocols require a password to be given, usually in combination with a password.

port => INTEGER

The port number behind which the service is hiding on the remote server.

proxy => PATH

The name of the proxy software (the protocol handler). This must be the name (preferable the absolute path) of your mail delivery software.

retry => NUMBER|undef

The number of retries before the sending will fail. If undef, the number of retries is unlimited.

timeout => SECONDS

SECONDS till time-out while establishing the connection to a remote server.

trace => LEVEL

username => STRING

Some protocols require a user to login.

via => CLASS|NAME

Which CLASS (extending Mail::Transport) will transport the data. Some predefined NAMEs avoid long class names: mail and mailx are handled by the Mail::Transport::Mailx module, sendmail and postfix belong to Mail::Transport::Sendmail, and smtp is implemented in Mail::Transport::SMTP.

The pop or pop3 protocol implementation can be found distribution Mail::Transport::POP3. For imap or imap4, install Mail::Transport::IMAP4.

Server connection

$obj->findBinary( $name, [@directories] )

Look for a binary with the specified $name in the directories which are defined to be safe. The list of standard directories is followed by the optional @directories. The full pathname is returned.

You may specify new(proxy), which specifies the absolute name of the binary to be used.

$obj->remoteHost()

Returns the hostname, port number, username and password to be used to establish the connection to the server for sending or receiving mail.

$obj->retry()

Returns the retry interval, retry count, and timeout for the connection.

DIAGNOSTICS

Warning: Avoid program abuse: specify an absolute path for $exec.

Specifying explicit locations for executables of email transfer agents should only be done with absolute file names, to avoid various pontential security problems.

Warning: Executable $exec does not exist.

The explicitly indicated mail transfer agent does not exists. The normal settings are used to find the correct location.

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.
