This is good to know! So your point about blocking AOL dialups is quite
valid; that is, we cannot depend on AOL to always provide 100% proxy
coverage. But those like myself still have to provide an alternative
port for our own customers who are using AOL. Sigh. Nothing like a
half-ahem job of doing something, eh? ;)

I understood that part. I was under the impression that some people
were considering looking at headers, in order to determine if a mail
"originated" from an AOL dial-up host, even though it was relayed
through another server. This is the idea I am trying to say would be
bad. (Maybe even before anyone actually thinks seriously about using
it, with any luck.)

To summarize: Do not assume that a mail is spam, just because the
originator used an AOL dial-up, and relayed it through a non-AOL server.

On the other hand, it is perfectly OK to refuse an incoming SMTP
connection directly from any AOL dial-up host; unless, like myself, you
have a specific reason to do allow it, and require proper
authentication.

The problem is the number of open relays out there. Sigh.
