Worked like a champ. Thanks!

Now, I know this is a FAQ, but I notice that when mail comes into an 
alias (say "address@hidden", my Yahoo!Groups alias), it can't 
find /home/egroups/.spamassassin.

Now, my question is this: Does the client (in this case, 
spamass-milter) tell spamd who to setuid() to, or does spamd try to 
determine that on its own?

Because if the client tells spamd who to become, it seems like it would 
be trivial to read the {rcpt_addr} macro, which already has all 
virtusertable lookups, etc., nonsense done. The only thing that you 
would do at that point is parse /etc/mail/aliases to map 
{rcpt_addr}->username (if needed), and then you could setuid() to the 
proper user, for their personal preferences, etc.
