Some list owners have recently noticed an increased number of bounces from
AOL members, giving an error that looks something like:
> ----- Transcript of session follows -----

AOL's given its members Mail Controls some time that lets them block mail
from particular addresses/domains. Recently, these controls were updated to
allow AOL members to block all Internet mail. A lot of them are doing this,
because of the deluge of UCE they're getting hit with.
As a byproduct, many list postings are also getting blocked. From my
experience, this isn't done maliciously, it's just a matter of the person
forgetting about the list they're on or not really thinking their actions
through properly.
I've done a lot of experimentation on this subject. As far as I can tell,
AOL's Mail Controls block the "Return-Path" header (though I have had some
inconsistent results). If your list has a static Return-Path (as most do, to
direct bounces to the list admin and not the message's sender), then you can
have them un-block that address, and they'll get your postings fine. Note
that depending on your list manager, the Return-Path from command responses
might be different from the Return-Path of your list postings (ie: LISTSERV
generates a blank Return-Path, and can't be un-blocked).
Have fun...
