>should the reverse DNS entry match the A record?
The reverse DNS entry should have an A record associated with it. For
example, if the reverse DNS entry is "mail.example.com", then
mail.example.com should have an A record (and it should point to the IP in
question). However, few mailservers will check that the A record exists,
and very few will check to see if the A record points back to the IP that
is being looked up.
>Our mail server is mail.areatech.com, but the reverse lookup shows
>66-140-194-140.areatech.com (SWBELL DNS).
That shouldn't cause a problem, since 66-140-194-140.areatech.com has an A
record (and it points back to correct IP).
