Same here :) I've just switched to use Cyrus Imapd here instead of
qpopper.

Sounds interesting.

Same here. I am doing this using a weird scheme composed with
bogofilter, spamassassin/razor and UCE native rules of my MTA.

Yup

Sounds good to me.

I like this approach and I am interested in implementing such a thing

Please tell me when you got something functionnal. I will on my side
try to do something closed to you.
