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. :)
