Wouldn't it be better if you enabled Sieve and use that instead? 
procmail needs shell access (or a very sophisticated web-upload thingy 
to weed out any shell escapes from procmail) to work and a user can 
easily create loops or break their mail reception completely.

Sieve at least makes sure the syntax is correct before installing a ruleset.
