Very nice!  I went out of my way to try nnfolder, which seems to be
the loveliest compromise between nnmbox and nnml (which I used before I
lost some mail).

Thanks for mentioning nnfolder... I'd truly recommend it for all the
procmail users out there.

How does this look (as a contribution to the Gnus FAQ)?

Q. I use procmail.  What is the most straightforward way to setup mail
reading under Gnus?

A. Gordon Matzigkeit <gord@enci.ucalgary.ca> writes:

After a long time (more than 6 months) of using Gnus with procmail,
I've come to the following conclusion: nnfolder is the best backend to
use.  It doesn't mangle your mail and require careful setup like nnmh
and nnml do (MH users may disagree), and it doesn't lump together all
the mail you so carefully separated in your .procmailrc (like nnmbox
or nnbabyl does).

So, put the following in your ~/.emacs:

;; automatically process nnfolder groups on startup
(setq gnus-secondary-select-methods '((nnfolder ""))
      gnus-activate-foreign-newsgroups 'gnus-level-subscribed)

;; procmail options
(setq nnmail-use-procmail t
      nnmail-split-methods nil     ;; don't do any internal splitting
      nnmail-spool-file 'procmail  ;; fetch mail from .spool files, not inbox
      ;; wait at least 2 days before deleting read mail
      nnmail-expiry-wait 2)


Put in your .procmailrc (probably after any other recipes you have):

#######################
# Gnus setup

# use lockfiles that Emacs movemail honours... otherwise you may lose mail
LOCKEXT=+
# put mail into our incoming Gnus spool
MAILDIR=$HOME/incoming
DEFAULT=mail.misc.spool

# Insert a Lines header to speed Gnus up
:0 fhw
* !^Lines:
* B ?? 1^1 ^(.|$)
| formail -a "Lines: $="

# ensure that there is a Message-Id and Subject line so Gnus doesn't barf
:0f
| formail -a Message-Id: -a "Subject: (none)"

######################################################################
# the rest of the .procmailrc contains rules to put mail into
# the different Gnus newsgroup spools

# the depot mailing list
:0
* ^TOinfo-cmu-depot@
list.info-cmu-depot.spool

# guile users
:0
* ^TOgel@
list.gel.spool

# Hurd developers
:0
* ^TOhurd-dev@
list.hurd-dev.spool

# Mach 4 users
:0
* ^TOmach4-users@
list.mach4-users.spool

# Lesstif users
:0
* ^TOlesstif-digest@
list.lesstif-digest.spool

# a test mailing list
#:0
#* ^Subject: test
#mail.test.spool

# anything that falls through the bottom will go to the mail.misc group

With the above setup, Gnus will detect new newsgroups automatically as
mail arrives in ~/incoming, so all you'll change in the future is your
.procmailrc.  When you subscribe to a new nnfolder group, you may want
to put (total-expire) in the group parameters (hit G p in the *Group*
buffer), so that mail will be semi-automatically deleted after
nnmail-expiry-wait days.

You should take a more detailed look into Gnus's mail expiry options
if total-expire doesn't sound right for you.
