Good question. Postfix has this feature where mail addressed to 
user+suffix is delivered to user, but if that user has a .forward+suffix 
file in his home directory, it follows the instructions contained 
therein. We're already making use of this feature, mail sent to 
report@bugs.python.org gets aliased to roundup+tracker, which delivers 
it to the roundup user and follows the instructions contained in 
.forward+tracker. I'm not sure what postfix does in the case where there 
was already a suffix on the original address.

I'm much more of an exim guy and I know this would be very easy in exim, 
but I suspect something might be possible using transports or something 
similar. This will require some research.
