safecat is another good suggestion.  it does the maildir delivery part 
safely.  excellent suggestion.

DOH!  you're right.  i don't know why i had assumed that condredirect was 
doing a delivery of the email as stdout from the command.  that was a 
dumb and obviously incorrect answer.

me, too, which is why i think i screwed up the answer.

to end up with the headers how about something like:

.qmail  and .qmail-default:

| condredirect user-spam /usr/bin/bogofilter -f -u 
| /usr/bin/bogofilter -f -u -p | /usr/bin/safecat ./Maildir/tmp/ ./Maildir/new/ 

.qmail-spam
| /usr/bin/bogofilter -f -u -p | /usr/bin/safecat ./Maildir/.SPAM/tmp/ ./Maildir/.SPAM/new/ 


this, too, like the previous crap i wrote, is untested.  :-).  does it 
even look reasonable?

the reason it's worth thinking about this is to do pop-enabled stuff for 
customers who may only be able to filter on headers.
