Although it is not required, an A record isn't too much to ask for a
mail server. I was bit by many hosts rejecting if there was no reverse
IP. I have since worked my mail server to pass everything at
www.dnsreport.com, mostly because of AOL.

If LOL is laughing out loud, what would AOL be?
I bet many can think of something that they
might not dare type!
