Thank you for your feedback!
After alking with my fellow postmasters at the other Universities in Norway, I
think I end up with rejecting spam like I do today, but silently dropping spam
from adresses that look like mailinglists. Something like this (need to add
regexp for VERP):
action_bounce("Spam-score ($hits) too high") unless ($Sender =~
/^(.*-request\@|owner-.*\@|.*-owner\@)/);
Maintaining yet another whitelist with addresses to offending list-servers
will not work. When users are unsubscribed it is already too late.
