Arnold,
I am surprised you don't have problems sending to AOL as well.
They don't accept email from servers that do not have reverse addresses.
I don't accept email from severs without reverse addressing. =09

Subject: Mailserver requirements
Today I run across a MTA which refused to accept mail because it could
not detect an MX record for the reverse mapping of the IP address of the
server which tried to deliver mail. Is this correct?
Or: if A is the IP Address of server trying to deliver mail, does
mx(reverse(A)) have to exist?
