Except that '^TO_' in procmail recipies is a variable that expands
into a regular expression that matches pretty much all of the possible
header lines that can contain the delivery address.  From
procmailrc(1):

       If the regular expression contains `^TO_' it will be substituted by
       `(^((Original-)?(Resent-)?(To|Cc|Bcc)|(X-Envelope
       |Apparently(-Resent)?)-To):(.*[^-a-zA-Z0-9_.])?)', which should catch
       all destination specifications containing a specific address.

There's another very similar pre-defined expression ^TO which I use --
I also match on the List-ID header, which is the most effective way of
catching messages delivered by through list: the ^TO stuff is to catch
messages CC'd to me as well as to the list:

    # FreeBSD Questions
    :0:
    * (^TO|^List-ID:.*)(freebsd-)?questions(\.|@)FreeBSD\.ORG
    | ${FORMAIL} -A"X-Folder: FreeBSD/Questions" >> FreeBSD/Questions

Note too that '.' in these REs is a wildcard, matching every single
character.  You need to escape it '\.' to match it literally.

	Cheers,

	Matthew
