MeTA1 1.0.PreAlpha23.0 (Default branch)
MeTA1 is a modularized message transfer agent (MTA)consisting of five (or more) persistent processes,four of which are multi-threaded. A queue managercontrols SMTP servers and SMTP clients to receiveand send email messages, an address resolverprovides lookups in various maps (including DNS)for mail routing, and a main control programstarts the other processes and watches over theirexecution. The queue manager organizes the flow ofmessages through the system and provides measuresto avoid overloading the local or remote systemsby implementing a central control instance. It issimple to configure using a C-like syntax and issecure and efficient.License: Other/Proprietary License with SourceChanges:
This release fixes a few bugs, most of which arerelated to createmap and the cdb map type. Two newfeatures were added. The interesting one is thatthe SMTP server now treats "Relaying denied"errors as "bad" commands. This means that thoserejections count for max_bad_commands_per_sessionand max_bad_commands_per_transaction. This isuseful when a client is broken enough to tryseveral relaying attempts.Image

NAME

       Net::SMTP::Server::Relay - A simple relay module for Net::SMTP::Server.

SYNOPSIS

	 use Carp;
	 use Net::SMTP::Server;
	 use Net::SMTP::Server::Client;
	 use Net::SMTP::Server::Relay;

	 $server = new Net::SMTP::Server('localhost', 25) ||
	   croak("Unable to handle client connection: $!
");

	 while($conn = $server->accept()) {
	   # We can perform all sorts of checks here for spammers, ACLs,
	   # and other useful stuff to check on a connection.

	   # Handle the client's connection and spawn off a new parser.
	   # This can/should be a fork() or a new thread,
	   # but for simplicity...
	   my $client = new Net::SMTP::Server::Client($conn) ||
	       croak("Unable to handle client connection: $!
");

	   # Process the client.  This command will block until
	   # the connecting client completes the SMTP transaction.
	   $client->process || next;

	   # In this simple server, we're just relaying everything
	   # to a server.  If a real server were implemented, you
	   # could save email to a file, or perform various other
	   # actions on it here.
	   my $relay = new Net::SMTP::Server::Relay($client->{FROM},
						    $client->{TO},
						    $client->{MSG});
	 }

DESCRIPTION

       The Net::SMTP::Server::Relay module implements simple SMTP relaying for use with the Net::SMTP::Server module.  All this module does is to
       take a given message and iterate through the list of recipients, doing DNS lookups for the associated MX record and delivering the
       messages.  This module makes extensive use of the plethora of other modules already implemented for Perl (specifically the DNS and
       Net::SMTP modules in this case), and should give but a glimpse of the potential for extending the Net::SMTP::Server's functionality to
       provide a full-featured SMTP server, native to Perl.

       The above example illustrates the use of the Net::SMTP::Server::Relay modules -- you simply have to instantiate the module, passing along
       the sender, recipients, and message.  More formally:

	 $relay = new Net::SMTP::Server::Relay($from, @to, $msg);

       Where $from is the sender, @to is an array containing the list of recipients, and $msg is the message to relay.
