This is what I use:

PATH=$HOME/bin:/usr/local/bin:/usr/bin:/bin
MAILDIR=$HOME/Maildir/
DEFAULT=$MAILDIR
LOGFILE=$HOME/.procmail_log

at the top of the procmailrc

:0:
* ^List-Id.*fedora-list.redhat.com
.Fedora\ User\ List/

for the Fedora List.
I use

* ^List-Id.*fedora-list.redhat.com

because that will only appear in the header of messages from the list.
If someone replies to me a CCs the list - their CC to me won't have that
header, so it doesn't get caught by the filter - allowing me to see it
in my regular inbox - but the copy that went to the list still gets
filtered to the list mail directory.
