I am hoping somebody can help me solve a problem I am having with 
procmail and spamassassin (specifically spamd). When spamassassin has 
marked a message as spam, it gets sorted to a Junk folder, but the 
problem is that it is owned by root:mail when it should be owned by the 
user. When this happens, dovecot will not serve the email to the user. I 
sort other emails into folders with simple matching rules and those work 
fine. Spamassassin is the only rule that is piped out to a program.

This is sort of a side comment but using spamd with .procmailrc is not
the best approach in my opinion. I beleve the .procmailrc below
provides a better way to do this. The INCLUDERC line runs the
spamassassin program. Spamd should be turned off if you do this.
PATH=$HOME/bin:/usr/bin:/global/bin:/usr/ucb:/bin:/usr/local/bin:
SHELL=/bin/sh
MAILDIR =       $HOME/Mail      # You'd better make sure it exists
LOGFILE =       $MAILDIR/procmail.log
LOCKFILE=       $HOME/.lockmail

#:0c
#!  akonstam@xxxxxxxxxxxxx
INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc

Using spamassassin rather than spamc gets around the SELinux issues, but 
I've read there are performance gains if you use spamd. I guess using 
spamassassin will work for me (my server isn't anywhere near being maxed 
out), but I think it'd be a good idea to resolve this issue for others 
to use later. I'm going to leave this open for a while, and if nothing 
comes of it, I'll post my results to both lists like I mentioned in 
another message.

How are you running spamassassin? Are you using anything like amavis?
If you have only procmail involved in the issue and use it on a per user
basis then it's really easy to handle.
$HOME/mail/spamjunk
As an example the above disposition line feeds the email to the user's
mail/spamjunk mbox file. Some appropriate rule ahead of the disposition
will tell procmail what to send to that folder.
I start my per user .procmailrc file with:
DROPPRIVS=yes
LOGNAME=procmail
I include likes like:
:0:
* ^From: Postmaster@xxxxxxxxxxxxxxxxxx
/dev/null
:0:
* ^From: AntiSpam UOL <.*@uol.com.br>
#/dev/null
/$HOME/mail/uol_crap
Then I call SpamAssassin with a more complex variant of:
:0
* < 500000
* !^List-Id: .*(spamassassin\.apache.\org)
| /usr/bin/spamc -t 150 -u jdow
Then I'm done with all mail being delivered to the mail folder and sorted
by up in the reader with an OE rule for spam.
Note that I pull down mail via a fetchmail, one fetchmail per actual user
regardless of the number of email accounts that are being fetched from.
