Procmail by default executes /etc/procmailrc before executing users
procmail files. So if you use procmail as your local filter,
you should be able to set up a single file for system wide filtering.
(I like procmail because it's so paranoid about file locks. I can have
two mail servers, one making delivery to nfs mounted spools, with
reasonable confidence they won't clobber the users mail. If only elm
were so considerate.)
