Another Procmail issue

Hi Again Susers! I run jhardins Sanitizer on my mailserver, and as far as I can tell it works nicely. I've tried reading the man pages for procmail and a few other items but I'm still unsure about one issue. Postfix uses procmail for delivery and in /etc I have the relevant files for the system, however what about locally for each user..if I create a procmailrc file in $home/user will that file run instead of the procmailrc file in /etc ?, or will it run after the /etc/procmailrc file? I would like hardins sanitizer to execute and after that for individual users to be able to add their on filtering rules or whatever? Anyway, which order are the procmailrc files executed, which takes precedence? Thomas
