[dspam-users] Solved! Trouble attempting to train the "globaluser"

I wrote the nice long e-mail below before I did some more experimentation and
log-watching. Hopefully this solution will help someone in the future.

For the impatient: You need to add "nobody" to the trusted user list for dspam
as that is the user postfix uses to fire off pipe commands.

Original e-mail follows --------------------------------------------------

As we move our mail system to postfix/dspam, I am attempting to set up aliases
that can be forwarded to by our existing mail system to train dspam [No, they
aren't on the same box, so I can't just add dspam to the chain. Nor would I
want to: it would require messing with the very fragile sendmail
config...which is why we're moving to postfix. But I digress.]

I set up the group file in /var/spool/dspam as described in the docs:

groupname:classification:*globaluser

I then added these lines to my aliases file:

train-spam: "|/usr/bin/dspam --user
globaluser --class=spam --source=corpus --mode=teft"

train-notspam: "|/usr/bin/dspam --user
globaluser --class=innocent --source=corpus --mode=teft"

Forwarding to them, however, gets bounced saying:

<train-notspam@host.name.com>: Command died with status 1:
    "/usr/bin/dspam --user globaluser --class=innocent --source=corpus
    --mode=teft"

However, running this command as the postfix user works, so I don't think it's
a permissions problem:

cat message | /usr/bin/dspam --user
globaluser --class=innocent --source=corpus --mode=teft

--------------------------------------

But see the opening of the message for my solution. :)
