It's commonplace these days for mail administrators to use RBL checks on inbound commections. One of the RBL lists has a heading for "dial-up blocks", or IP's which are dynamically assigned to dial up clients, or dynamic allocation IP addresses - which means that if the email *is* spam, it can't necessarily be tracked effectively. My mail server does exactly what AOL's does - denies the connection. A work around is to relay your outbound mail through your ISP's "legitimate" mail server - that way, AOL will see it coming from a non-dynamic IP, and accept the message. This, of course, depends on your ISP allowing you to relay through it.
