AOL rejects the notification email as spam.
The problem is due to no rDNS (reverse DNS, PTR record) on the IP used when sending email. It is well known that AOL, and a number of other ISPs, is rejecting mail when the sending site has no rDNS.
This affects more than reply notifications. It also prevents AOL members from joining evcforum, for they will not receive the email notification of their site password. It also prevents AOL members from changing their email address (unless to a non-AOL address), for the same reason.
