Alice, you may be a lifesaver! Are you considering to also take a fresh
look at rouncube plugins? There is one thing I couldn't find. On my mail
servers I use amavis as a superstrcture above spamassassin and clamav. And
there is a way to have users individual spam/virus preferences in mysql
database (alas, postgresql didn't work in all my attempts). And the only
missing thing here I never found is how to give users a way to edit their
whitelist/blacklist preferences. There is long list of things I tried to
harnes... so far amacube is the closest to giving users the way to edit
preferences, and only whitelist/blacklist is missing from it.

Thanks a lot for all your efforts!!
