    Only one way: Send email to this address. If it bounced back with delivery error - it means does not exist.

    Please Clear me The Following Details
    var $user;
    var $domain;
    var $port = 25;
    var $max_conn_time = 30;
    var $max_read_time = 5;
    var $from_user = 'user';
    var $from_domain = 'localhost';
    var $debug = false;

    is that port no will be changed frequently?
    user should be the control panel details?

    as i am getting the following errors

    Array ( [0] => pbminfotech.com [1] => pbminfotech.com ) try pbminfotech.com:25
