I'm administrator/moderator of several Mailman mailing lists through my hosting service hostmonster.com.

One of the lists MBRS@OptimistClubOfStAndrews.org <mailto:MBRS@OptimistClubOfStAndrews.org> is bouncing to addresses with sc.rr.com and earthlink.com domains.

I've deleted and rebuilt the list at least once, more I think. The bounces continue.

I would have been very surprised if that helped.

My first guess is that those domains are blocking mail from your Mailman server, but if your other lists send to those domains OK, that isn't it.

First, ensure you get bounce notices by ensuring that bounce_notify_owner_on_disable and if your Mailman is 2.1.19 or newer bounce_notify_owner_on_bounce_increment are set to Yes on the list admin Bounce processing page.

Then, when you get a notice with the DSN attached, send us the DSN so we can see why the messages are bouncing. Then we may be able to suggest things.
