hmm... good idea, but how does one bounce a missed spam to that account
with outlook ? I think that's not even possible with moz ?
My scenario: RHEL server with the accounts; several windoze/outlook users
who POP3 the accounts

I've installed openwebmail.org so the users can review their spam
themselfs (all spam is directed to ~/mail/SPAM and this is moved once a
week to SPAM2 -> SPAM3 -> dropped), so moving the spam to a general
account is easy.
This also has a very nice side-effect. Users have to log in to openwebmail
at least once to activate spam removal - the ~/mail/ directory is created.
If they don't log in, spam is just tagged and delivered.

Same here *g* ;-)
