It looks to me like bellsouth.com uses messagelabs.
bellsouth.com MX preference = 20, mail exchanger =

This is much more than rumor. In addition to regex style filters that
look for generic/dynamic looking PTR
+1 to everything that Jason wrote. These conditions are only going to

I am using zoneedit.com to host the DNS for all of the sites, I made the
changes to these 2 domains, along with 5 others over 3 weeks ago. I haven't
changed any entries since then so it worries me that you saw different A
records. We are doing the actual hosting of the sites.
