Doh!

*sound of Terje slapping his forehead*

Trying to always find the solutions on own my I've gone through the example
configs, documentation, mailing list (searching it went surprisingly fast
using mutt against the anonymous imap folder) etc.

Since I forgot to actually check out imapd.conf, probably as a result of
having been used to always finding the answers in the well commented example
config, the most important answer just had to be here.

/me goes to sit in the corner for a while.

Thankfully I'm using postfix, so I'll be able to block these addresses as
needed :)

This is actually the perfect answer to what I was looking for.

Only limitation is that without sieve filtering I'm left without the ability
to properly filter mailing lists administered elsewhere which I subcribe to as
a regular user to archive for public use at my site.

I could always stack a procmail in front of this, but then I'm back to an
extra process fork.  Chances that someone will abuse this have historically
speaking been pretty low, so the option of implementing better access control
on a need by need basis is there.

Lots of grateful thanks,
