Where are you getting this from? When I look up smtp.azcom.net, the
name doesn't exist. And azcom.net resolves to a different address.

The name reported by ping comes from a reverse DNS lookup of the
address. So you need to change the PTR record to point to
smtp.azcom.net.
However, since PTR records are required to point to primary names, not
aliases, you would also have to change smtp.azcom.net from a CNAME to an
A record.
