Maildir++, Dovecot, & Procmail

I am using Dovecot with Maildir++ IMAP storage and using Procmail with Dovecot’s LDA deliver. Using Dovecot’s LDA with Procmail ensures the appropriate cache files in the Maildir++ folders are updated on delivery. This can improve performance as the Dovecot IMAP or POP3 server does not need to re-index the folders after each new delivery.

My system-wide /etc/procmailrc contains:

SHELL=/bin/sh
LOGFILE=/var/log/procmail.log
ORGMAIL=$HOME/Maildir/
DEFAULT=$HOME/Maildir/
MAILDIR=$HOME/Maildir/
DELIVER=/usr/lib/dovecot/deliver
:0 w
* ^X-Spam-Status: Yes
| $DELIVER -m Junk
:0 w
| $DELIVER

Some examples from my personal $HOME/.procmailrc:

DELIVER=/usr/lib/dovecot/deliver

# logcheck
:0
* ^To: logcheck@etherknet.com
| $DELIVER -m INBOX.Etherknet.Administration.logcheck

# DenyHosts
:0
* ^From: DenyHosts <denyhosts@etherknet.com>
| $DELIVER -m INBOX.Etherknet.Administration.denyhosts

# Facebook
:0
* ^From: .*@facebookmail.com
| $DELIVER -m INBOX.Personal.Facebook

:0 w
| $DELIVER

Lastly, some examples from my logs:
