How to Fix Reverse DNS?

[Lyle Giese]

You don't fix this, AT&T needs to be told to fix it.  I assume you have 
static IPv4 addresses?  You don't seem to have an MX record at all.

The way AT&T will update this is if your MX record(or backup MX record) 
points to this ip address and then they should honor a request to set 
the reverse lookup for you.
