We have a site: http://eaachat.org/
with several mailing lists. We have some lists advertised on a non-default public list info page that we "branded" (thank you Mark for your help!) here: http://eaachat.org/maillist.html
and shows only the publicly accessible pages.
These pages have a mailto: owner@eaachat.org which is forwarded to list@eaachat.org. We all have various filters set in our MUA to cope with this. We check the moderator pages of the public lists frequently for legitimate help requests, in other words the admins are the spam filters for the domain.
The default mailman list info page is here: http://lists.eaachat.org/mailman/listinfo
All lists are closed to non member posts and the subscribe policy is confirm and approve.
My question is - are spamers able to pick up lists from the default (but not easily accessible) default mailman listinfo page and start bombarding us with spam on all lists? Or should I set the "Advertise this list" option to "no" for the lists on the default listinfo page?
Thank you,
Dennis
