I too am having some problems, but I have a hunch as to the root of the issue and I'd like to get some advice to get this working the way I'd like.
I currently have one "admin_user" set up to administer the various domains and websites that I'm hosting. I would like to set up procmail such that it operates on all of the emails under that admin user, however I don't know if this is possible the way DH has this set up. Is there a way to do this?
If not, what is the cleanest way to have one admin user per domain that will allow the oversite of procmail? If that is not possible...
What do I need to do in order to change a pXXXXXX user into a shell account user so that I don't have to go recreating users and email addressses and such?
