SYNOPSIS



    use Net::Server::Mail::ESMTP;

    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::ESMTP socket => $conn;
        # activate some extensions
        $esmtp->register(Net::Server::Mail::ESMTP::8BITMIME);
        $esmtp->register(Net::Server::Mail::ESMTP::PIPELINING);
        # 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 ESMTP (RFC 2821) protocol.

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

METHODS

ESMTP specific methods.

    register

Activate an ESMTP extension. This method takes a module’s name as argument. This module must implement certain methods. See Net::Server::Mail::ESMTP::Extension for more details.

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.

    EHLO

Takes the hostname given as argument. Engage the reverse path step on success. RFC 2821 require thats EHLO command return the list of supported extension. Default success reply implement this, so it is deprecated to override this reply.

You can rebuild extension list with get_extensions() method.

Exemple:



    my @extends;
    foreach my $extend ($esmtp->get_extensions())
    {
        push(@extends, join( , $extend->keyword(), $extend->parameter()));
    }
    my $extends_string = join("\n", @extends);
