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

        elsif(not(grep $domain eq $_, @local_domains))
        {
            return(0, 554, "$recipient: Recipient address rejected: Relay access denied");
        }

        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)
