Extremely reliable. They are created by a company that is dedicated to
E-mail and Spam and DNS.

 

Problem is you have a CNAME within your MX record. That is a big no no and
can cause problems and is non-compliant with Internet standards as discussed
in the RFC's. When your server answers, it is claiming to be someone
different.

 

You are also not accepting e-mail to abuse@xxxxxxxxxxxxx and
postmaster@xxxxxxxxxxxxxx That is grounds for listing under RFCignorant.org
and is again non-compliant with RFCs.

 

In this day and age of SPAM and Viruses, if you are going to have a e-mail
server, you better play by the rules.

 

BTW, many mail servers will either not accept mail from yours or silently
delete e-mail from your server because of the above mentioned problems.

How reliable are these tests?

 

I just did the same test on our MX records and we're not having any issues
what so ever.

 

 

 

This means that the 207.61.92.122 domain does not exist!  No mail can be
sent to it.

You do have some DNS problems with your MX record:
