I don't think this has already been posted as a suggestion (and I even looked

).
But in regards to
this thread I'd really like to see this incorporated in an integrated fashion into ISPConfig.
Unfortunately, spam is now a fact of life on the 'net. ISPConfig's integrated spam checking is really slick -- but it seems not fully done without dropping that spam into a user's default Spam folder if Maildirs are enabled.
