Procmail with Dovecot

[Marc Roos]

No need for user shell access. Before switching to sieve, I made some 
email interface where users could turn on 'services' by sending an email 
to themselves.

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.
