The qmail FAQ gives this command:
In /.qmail add the line
| preline procmail
Version 3.11pre7 has changed the default mail box variable. It used to be in config.h. It is now in src/authenticate.c:
#define MAILSPOOLHOME "/Mailbox" /* watch the leading / */ /* delivers to $HOME/Mailbox */
I have culled from comp.mail.mh ans comp.mail.misc some hints on a .procmailrc file. Thanks to everyone!

Procmail is an excellently documented program. Read the man pages for examples on how to set up your .procmailrc file.
