Personal stupidity, which is the reason why I asked here.

This seems to do the trick with only one router, thanks.

Your solution has a little too many side effects, IMO, and has
influence on the real- router which we really have for a long time.
How would you handle, in your solution, the case that it is desired to
have mail for, say, uucp (UID 8) be delivered to the mail store of the
user uucp? Aliasing it to itself in the system aliases file won't work
here.
Another argument for having our own alias file for low-uid users is
that /etc/aliases may be used by different MTAs on Debian systems as
well, and I'd like to keep its semantics as closely as possible to
what one expects of an /etc/aliases file on a Unix system.
