7. Procmail

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.
