BTW, I'd be happy to share my wordlist. At ≈12MB it's kinda large though.

I've defined two macros in Mutt; for training bogofilter to see a
message as Ham or Spam;

macro index S "<enter-command>unset wait_key\n\
<pipe-entry>bogofilter -Ns\n\
<enter-command>set wait_key\n\
<delete-message>" "requalify and delete message as spam"

macro index H "<enter-command>unset wait_key\n\
<pipe-entry>bogofilter -Sn\n\
<enter-command>set wait_key\n" "requalify message as non-spam"

This is for my personal database, of course. 

But if users can send spam to a special mailbox, it should not be too hard to
run that through bogofilter as training material in a cron-job.

That is possible. Look at the bogofilter FAQ.
