Net::Server::Mail::SMTP - A module to implement the SMTP protocole SYNOPSIS
use Net::Server::Mail::SMTP; 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 $smtp = new Net::Server::Mail::SMTP socket => $conn; $smtp->set_callback(RCPT => &validate_recipient); $smtp->set_callback(DATA => &queue_message); $smtp->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 $msgid"); } DESCRIPTION
This class implement the SMTP (RFC 821) protocol. Notice that it don't implement the extension mechanism introduce in RFC 2821. You have to use Net::Server::Mail::ESMTP if you want this capability. This class inherit from Net::Server::Mail. Please see Net::Server::Mail for documentation of common methods. METHODS
SMTP specific methods. get_sender Returns the sender of the current session. Return undefined if the reverse path step is not complete. get_recipients Returns the list of recipients supplied by client. Returns undef if forward_path step is not engaged. Returns an empty list if not recipients succeed. EVENTS
Descriptions of callback who's can be used with set_callback method. All handle takes the Net::Server::Mail::SMTP object as first argument and specific callback's arguments. HELO Takes the hostname given as argument. Engage the reverse path step on success. sub helo_handle { my($session, $hostname) = @_; if($hostname eq 'localhost') { return(0, 553, q(I don't like this hostname, try again.)); } # don't forgot to return a success reply if you are happy with # command's value return 1; } NOOP This handler takes no argument EXPN Command not yet implemented. Handler takes address as argument. EXPN Command not implemented, deprecated by RFC 2821 Handler takes no argument. VRFY Command not yet implemented. Handler takes address as argument. HELP Command not yet implemented. Handler takes a command name as argument. MAIL Handler takes address as argument. On success, engage the forward path step and keep the given address for later use (get it with get_sender() method). RCPT Handler takes address as argument. On success, engage the mail data path step and push the given address into the recipient list for later use (get it with get_recipients() method). SEND Command not implemented. Handler takes no argument. SOML Command not implemented. Handler takes no argument. SAML Command not implemented. Handler takes no argument. DATA This handler is called after the final . sent by client. It takes data as argument in a scalar reference. You should queue the message and reply with the queue ID. DATA-INIT This handler is called before enter in the "waiting for data" step. The default success reply is a 354 code telling the client to send the mail content. DATA-PART This handler is called at each parts of mail content sent. It takes as argument a scalar reference to the part of data received. It is deprecated to change the contents of this scalar. RSET Handler takes no argument. On success, all step are initialized and sender/recipients list are flushed. QUIT Handler takes no argument. Connection is closed after this command. This behavior may change in future, you will probably be able to control the closing of connection. SEE ALSO
