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.

Dear All,
I am running Exim4 4.84.2-1 on Debian Jessie. I was getting error while
sending mails to certain domains, but mails were going to domains like
gmail, yahoo etc. Then I installed a self certified certificate and a
SSL
certificate and enabled TLS, assuming issue was with TLS. Still the
following errors are appearing when sending mails to certain domains.

Because of this, mails are not going to certain domains.
Can anyone tell me what is the issue and how to solve this?
