Sendmail, dovecot, squirrelmail and Maildir

I had to advise somebody today on how to configure sendmail/dovecot/squirrelmail with Maildir. There really is no excuse not to switch to Maildir; it's both faster than mbox and supports sub directories!
I know this works on Fedora 4/5 so I just thought I'd post the config before I forget:

/etc/procmailrc (just the one line needed)
DEFAULT=$HOME/Maildir/

/etc/dovecot.conf (replace the appropriate line in your existing config)
default_mail_env = maildir:/%h/Maildir

/usr/share/squirrelmail/config/config.php (this section is near the beginning of the file)
$domain = 'yourdomain.com';
$imapServerAddress = 'localhost';
$imapPort = 143;
$useSendmail = true;
$smtpServerAddress = 'localhost';
$smtpPort = 25;
$sendmail_path = '/usr/sbin/sendmail';
$pop_before_smtp = false;
$imap_server_type = 'courier';
$invert_time = false;
$optional_delimiter = '.';
$encode_header_key = '';
