Does the MX record of the fully qualified domain name used as an MX record matter?
For example, let's say that example.com
has MX records which point to:
mx01.example.com
mx02.example.com
But mx01.example.com
and mx02.example.com
each have their own MX records which point to:
mx01.googlemail.com
mx02.googlemail.com
The individual A records of mx01.example.com
and mx02.example.com
are correct for the sending and receiving of email for example.com
, but can their own MX records interfere with anything if it's set to something else?
