I've noticed that certain lists "role" accounts are being spoofed (by
viruses) in FROM: fields. Thus you may encounter:
mail from: listname-SUBSCRIBE-REQUEST@listhost
mail to: listname-SUBSCRIBE-REQUEST@listhost
Because the particular listname was SERVICE=LOCAL and SUBSCRIPTION=OPEN,
the process succeeded.
I've done a
QUIET SERVE listname-SUBSCRIBE-REQUEST OFF
and was still able to use the auto-subscribe role address (that's a good
thing).
