Couple things.....

You should be trying more than just the one address. They have more than a single mx record. One should hopefully be valid.

Check to see if you're getting stale data from an old cached response.

(cynic@paranoia)(03:39pm:10/28/10)
(~)> host -t mx bellsouth.net
bellsouth.net mail is handled by 10 gateway-f1.isp.att.net.
bellsouth.net mail is handled by 10 gateway-f2.isp.att.net.
(cynic@paranoia)(09:25am:10/29/10)
gateway-f1.isp.att.net has address 204.127.217.16
(cynic@paranoia)(09:25am:10/29/10)
gateway-f2.isp.att.net has address 207.115.11.16
(cynic@paranoia)(09:25am:10/29/10)
(~)> host -t soa bellsouth.net
bellsouth.net has SOA record auth-dns.asm.bellsouth.net. hostmaster.bellsouth.net. 2010100101 1800 900 432000 10800

So they're using what looks like a date as the serial, and to me it looks like it was updated fairly recently. They have a fairly long expire time, so it could happen that there' s old crap in a cache between you and a dns update.

I'll go reboot the internet real quick. Let me know if it clears up :)

In the mean time, see what you're getting for the soa data. They may have a lame nameserver too, but the responses I get back from the authoritative nameservers is valid. If the serial is different than the one above, that's a big hint that there's something rotten in a cache waiting on expiration.

If the serial you get does not line up with the answers you get from their official name servers, then you have a cache problem somewhere.

I have verizon FIOS but I forget if I use their DNS or OpenDNS.

Either way, I can see it:
