NetSDS::App::SMTPD

use NetSDS::App::SMTPD

Needs for work with socket. This module is a parent for NetSDS::App::SMTPD and NetSDS::App::SMTPD::Client and a child of a NetSDS::APP

ITEMS

Creating a simple socket which could be transformed into a listening in NetSDS::App::SMTPD and could be used in NetSDS::App::SMTPD::Client for accept connection
This method uses for making a timeout before connections to the server: if there is no connections to accept, program would be just waiting in select while the connection appeared.
Close socket

Provides the smtp protocol bu using Net::Server::Mail::SMTP. Had attributes: smtp - an object of Net::Server::Mail::SMTP, ip - ip of the remote host, headers - ref hash with headers of a message, msg - a body of a message.

ITEMS

All that subs do - its only call the methods of a Net::Server::Mail::SMTP with the same name.
In this sub we parse message and set headers of the object and message body. This sub is call as a callback on event DATA
Get methods that make you access to a header of a msg and message body. Example: $client->get_header('FROM') or $client->get_header('to');

This module init a smtp-server.

ITEMS

Init a listening socket by creating a simple socket Super::create_socket and make it listening.
Takes - a message that has been received, parses them and prepare the structure of headers, body for next actions
Waiting for an smtp connection and that accept it.

        #!/usr/bin/env perl
        use strict;
        use warnings;
        Receiver->run(
                infinite  => 1,
                debug     => 1,
                verbose   => 1,
                conf_file => '../conf/mts-receiver.conf',
        );
        1;
        package Receiver;
        use base 'NetSDS::App::SMTPD';
                                    
        sub process {
                my $self = shift;
                my $client = $self->SUPER::process;
                #do something with msg;
                my $from = $client->get_header('from');
                my $msg = $client->get_msg;
                .....
                return $self;
        };

or you could reinit process like this:

        sub process {
                my $self = shift;
                my $client = $self->accept;
                return unless $client;
                $client->process;
        
                #do something
                ......
                $client->close;
                return $self;
        };
