NAME

       Net::Server::Mail::LMTP - A module to implement the LMTP protocole

SYNOPSIS

	   use Net::Server::Mail::LMTP;

	   my @local_domains = qw(example.com example.org);
	   my $server = new IO::Socket::INET Listen => 1, LocalPort => 25;

	   my $conn;
	   while($conn = $server->accept)
	   {
	       my $esmtp = new Net::Server::Mail::LMTP socket => $conn;
	       # adding some handlers
	       $esmtp->set_callback(RCPT => &validate_recipient);
	       $esmtp->set_callback(DATA => &queue_message);
	       $esmtp->process();
	       $conn->close()
	   }

	   sub validate_recipient
	   {
	       my($session, $recipient) = @_;

	       my $domain;
	       if($recipient =~ /@(.*)>s*$/)
	       {
		   $domain = $1;
	       }

	       if(not defined $domain)
	       {
		   return(0, 513, 'Syntax error.');
	       }
	       elsif(not(grep $domain eq $_, @local_domains))
	       {
		   return(0, 554, "$recipient: Recipient address rejected: Relay access denied");
	       }

	       return(1);
	   }

	   sub queue_message
	   {
	       my($session, $data) = @_;

	       my $sender = $session->get_sender();
	       my @recipients = $session->get_recipients();

	       return(0, 554, 'Error: no valid recipients')
		   unless(@recipients);

	       my $msgid = add_queue($sender, @recipients, $data)
		 or return(0);

	       return(1, 250, "message queued $msgid");
	   }

DESCRIPTION

       This class implement the LMTP (RFC 2033) protocol.

       This class inherit from Net::Server::Mail::ESMTP. Please see Net::Server::Mail::ESMTP for documentation of common methods.

EVENTS

       Descriptions of callback who's can be used with set_callback method. All handle takes the Net::Server::Mail::ESMTP object as first argument
       and specific callback's arguments.

       LHLO

       Same as ESMTP EHLO, please see Net::Server::Mail::ESMTP.

       DATA

       Overide the default DATA event by a per recipient response. It will be called for each recipients with data (in a scalar reference) as
       first argument followed by the current recipient.

DESCRIPTION

       This class implement the SMTP (RFC 821) protocol. Notice that it don't implement the extension mechanism introduce in RFC 2821. You have to
       use Net::Server::Mail::ESMTP if you want this capability.

       This class inherit from Net::Server::Mail. Please see Net::Server::Mail for documentation of common methods.

METHODS

       SMTP specific methods.

       get_sender

       Returns the sender of the current session. Return undefined if the reverse path step is not complete.

       get_recipients

       Returns the list of recipients supplied by client. Returns undef if forward_path step is not engaged. Returns an empty list if not
       recipients succeed.

EVENTS

       Descriptions of callback who's can be used with set_callback method. All handle takes the Net::Server::Mail::SMTP object as first argument
       and specific callback's arguments.

       HELO

       Takes the hostname given as argument. Engage the reverse path step on success.

	   sub helo_handle
	   {
	       my($session, $hostname) = @_;

	       if($hostname eq 'localhost')
	       {
		   return(0, 553, q(I don't like this hostname, try again.));
	       }

	       # don't forgot to return a success reply if you are happy with
	       # command's value
	       return 1;
	   }

       NOOP

       This handler takes no argument

       EXPN

       Command not yet implemented.

       Handler takes address as argument.

       EXPN

       Command not implemented, deprecated by RFC 2821

       Handler takes no argument.

       VRFY

       Command not yet implemented.

       Handler takes address as argument.

       HELP

       Command not yet implemented.

       Handler takes a command name as argument.

       MAIL

       Handler takes address as argument. On success, engage the forward path step and keep the given address for later use (get it with
       get_sender() method).

       RCPT

       Handler takes address as argument. On success, engage the mail data path step and push the given address into the recipient list for later
       use (get it with get_recipients() method).

       Command not implemented.

       Handler takes no argument.

       SOML

       Command not implemented.

       DATA

       This handler is called after the final . sent by client. It takes data as argument in a scalar reference. You should queue the message and
       reply with the queue ID.

       DATA-INIT

       This handler is called before enter in the "waiting for data" step. The default success reply is a 354 code telling the client to send the
       mail content.

       DATA-PART

       This handler is called at each parts of mail content sent. It takes as argument a scalar reference to the part of data received. It is
       deprecated to change the contents of this scalar.

       RSET

       Handler takes no argument.

       On success, all step are initialized and sender/recipients list are flushed.

       QUIT

       Handler takes no argument.

       Connection is closed after this command. This behavior may change in future, you will probably be able to control the closing of
       connection.
