The issue is called DMARC, and most certainly with a reject policy,
which basically tells recipients to reject messages that doesn't quite
appear to come from the originator.
This is problematic for mailing lists, that kind of act as a middle
man, and even moreso because rejections end up as bounces to the
mailing list software, which will end up disabling the bouncing
address. So in the end, it becomes a story of how users from one
domain are capable of throw out everyone else that checks their DMARC
Last time we went through this, we ignored the problem, for reasons I
cannot remember now. I'll have a closer look at what mailman can
offer and get back to you.
