You can use services like http://checktls.com/perl/TestSender.pl to test
your SSL settings. This error:
550 Access denied - Invalid HELO name
indicates that you haven't set the PRIMARY_HOST_NAME to your actual
fully qualified host name mail.rajagiritech.ac.in. And your domain name
rajagiritech.ac.in doesn't have a mx-entry.
