The out-of-the-box selinux policy for FC5 was somewhat broken for
procmail, particularly if you wanted to forward mail as an action.
Paul, what log files are you trying to write, and what the the "adv:

Gregory, is /save/home/$USER the home directory for $USER?
What's the output of:
$ ls -laZ /save/home
