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

We mostly have the Plain option ticked. Is that RFC 934? And unticked is Mime?

I can’t see an obvious pattern, but I several unticked that aren’t
marked bouncing. There are also some ticked that aren’t marked
bouncing, but I can tell if these have fixed the problem themselves
(if that’s possible), or have perhaps whitelisted us.

I’ll have a more thorough look, and if there’s a pattern, we can try
unticking them all.

I’ll try contacting bigpond, but as a non customer, I suspect I’ll be
ignored at best. In my own organisation, a young colleague wanted to
leave our new spam filter on the default setting to quarantine all
mailing list emails, which it called “suspicious newsletters”. He
thought our users would appreciate that. I suspect many tech support
people think the same way.
