Justin, Well, maybe. I've had the edns0 problem in the past with a couple of clients. But, more likely, it's one of the recent problems I've had with clients of mine sending to AOL:
1) As of a couple of months ago, AOL no longer accepts mail from servers that do not have PTR records defined. 2) AOL has its own internal scanning mechanisms to try to identify and block domains and/or subnets attempting to spew spam to AOL subscribers. Even though a particular domain/subnet may not appear on any RBL lists, AOL could still be blocking it. To determine which it is, telnet to port 25 on one of the AOL SMTP servers and try to manually send a message to a valid AOL address. Make sure you do this from the actual Exchange server on which the AOL queues are filling up. The error message you will receive from the AOL server will include a link to a website that will explain the reason why AOL will not accept a connection from you. In my most recent case, my client switched ISP's and, by chance, received a set of IP addresses that had been blocked by AOL for a long time. AOL tech support was TOTALLY unresponsive and it took me about 6 weeks and many, many phone calls to AOL to finally get the subnet removed from their blocking lists. Be prepared for a lot of pain dealing with AOL on this. As soon as you determine the problem, please let us know so I can bill Michael for $0.25. :-) Steve --- "Michael B.
