[Dovecot] Dovecot deliver and procmail

[Václav Hůla]

Hi,
I have site w. around 7000 users, most of which have some procmail rules 
(theres even .procmailrc in /etc/skel with rule to put spam into spam 
folder). Afaik dovecot's deliver doesnt understand procmail rules, so 
i'd like to ask if its possible to configure procmail so it saves mail 
using deliver, without modifying users .procmailrc

Thanks for any pointers,
Vaclav Hula
