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.
