NAME

       Net::SMTP::Server::Client - Client session handling 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::Client module implements all the session handling required for a Net::SMTP::Server::Client connection.  The above
       example demonstrates how to use Net::SMTP::Server::Client with Net::SMTP::Server to handle SMTP connections.

       $client = new Net::SMTP::Server::Client($conn)

       Net::SMTP::Server::Client accepts one argument that must be a handle to a connection that will be used for communication.

       Once you have a new client session, simply call:

       $client->process

       This processes an SMTP transaction.  THIS MAY APPEAR TO HANG -- ESPECIALLY IF THERE IS A LARGE AMOUNT OF DATA BEING SENT.  Once this method
       returns, the server will have processed an entire SMTP transaction, and is ready to continue.

       Once $client->process returns, various fields have been filled in.  Those are:

	 $client->{TO}	  -- This is an array containing the intended
			     recipients for this message.  There may be
			     multiple recipients for any given message.

	 $client->{FROM}  -- This is the sender of the given message.
	 $client->{MSG}   -- The actual message data. :)

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.
