><br>> Fallout from above problem: lots of people on various chambana lists are being set to "NOMAIL". Today that included Carol/Aaron, and Rev. Underwood, from CUCPJ Discuss list. Mailman does this when it gets a fatal bounce, as happens when receiving sites reject mail due to our sender being flagged as a spam source...<br>

><br>> Found more about why <a href="http://chambana.net/209.66.96.68">chambana.net/209.66.96.68</a> is *still* being listed as a spam source: there's no reverse DNS for that IP address.
