Thanks Travis,
I was so intent on looking at the RDNS (our DNS server) that I neglected to look at
his DNS server. I appreciate the info.

I am guessing that he is looking at the SMTP log files and he is guessing that from the greeting he is having problems - if indeed there really aren't any. On Friday I received a greeting that said I was being blocked and then was disconnected with a 550. I called AOL and after about 20 minutes and after getting to a Level 3 engineer - they told me Ooops. We have been having troubles our bad.
www.DNSReport.com shows you have serious issues here with the DNS setup. http://www.dnsreport.com/tools/dnsreport.ch?domain=tommydew.com
AOL shows there is RNDS for 207.212.194.225. http://postmaster.aol.com/tools/rdns.html
My guess is that the RDNS is fine. Everything else is hosed.
