NAME

Net::Server::Mail::ESMTP::AUTH - SMTP Authentification extensions for Net::Server::Mail::ESMTP

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 AUTH extension
    $esmtp->register('Net::Server::Mail::ESMTP::AUTH');

    # adding AUTH handler
    $esmtp->set_callback(AUTH => \&validate_auth);
    $esmtp->set_callback(DATA => \&queue_message);
    $esmtp->process;
  }

  sub validate_auth
  {
    my ($session, $username, $password) = @_;

    if ($username eq 'ROBERT' and $password eq 'TOTO04') {
      # AUTH SUCCESFULL
      $session->{AUTH}->{ok} = 1;
      return 1;
    } else {
      # AUTH FAILED
      return 0;
    }
  }

sub queue_message { my($session, $data) = @_;

    # providing AUTH doesn't make it mandatory.
    # A client might not use AUTH at all!
    # You must deal now with permissions:

    unless ($session->{AUTH}->{ok}) {
        # warn "no AUTH supplied!";
        return(0, 530, 'Error: Authentication required');
    }
    ... do stuff
}
