Don't be so hard on yourself. :)

Glad it worked.

Would this do the trick?

uucp: /var/mail/uucp

How am I changing the semantics of /etc/aliases? Local parts that appear
in that file get redirected just like they always have, regardless of
whether or not they happen to be the names of system accounts on the
machine. If anything, you're changing the semantics, not me, because
with your solution, system account names must be put in your new file
instead of in /etc/aliases the way they always have. There exist (or at
least there have existed in the past) some debian packages that append
entries to that file in their maintainer scripts, so those packages may
not behave properly with your proposal.

Anyway, like I said near the end of that bug report, the solution I
proposed works fine for me, and I'm not using the debian config file, so
don't worry about offending me by rejecting the suggestion for your
packaging.
