Many isps do intercept/block port 25 I don't know if aol does. AFAIK, it
didn't in the past but it may now that it offers IMAP/SMTP. There is also no
real reason for AOL servers to be blacklisted, except by vigilantes or
elitists. They have a good antispam policy in their TOS that should keep
them off all black lists.

your AOL Q's wrt propriety services - see the faq link at the end for more.

Thanks for the info. I just got a 554 from mail.com, although I'm sure AOL
returns the courtesy (figuratively speaking, of course).

Are you sending through mail.com SMTP servers to aol or from aol to
mail.com? I'm pretty sure mail.com is on a lot of RBLs - I know I block
outblaze.com because of spam (and mail.com uses their servers).
