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

INHERITANCE
     Mail::Transport::SMTP
       is a Mail::Transport::Send
       is a Mail::Transport

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.

          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] )
        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

        Inherited, see "Error handling" in Mail::Reporter

        Inherited, see "Error handling" 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.
