While that's not particularly difficult, I thought it was possible to
have /etc/aliases route to an additional user more simply than your method.

I'm _fairly_ sure (keeping in mind that I don't use Postfix!) that you can
have an entry like:

user1: user2, user3 at otherhost

where all mail to "user1" goes to "user2 at localhost" and "user3 at otherhost",
what I'm not so sure about is whether there's a syntax to allow mail
to "user1" to be sent to "user1" and _also_ "user2" - since that runs the
real risk of a mail loop, perhaps not :-)
