[Mailman-Users] Digest members of one domain marked bouncing

[Peter Shute]

Recently we've had a lot of members from one particular domain (
bigpond.com/bigpond.com.au) marked bouncing, and it looks like it's only
digest members who are affected. I haven't checked yet if all digest
members from that domain are affected. We unticked their nomail box, but a
few days later they're marked bouncing again.

I'm guessing that for some reason, that mail server thinks our digest
emails are spam. Any ideas what to do about this?
