Sigh - I didn't think of that.

Do you feel this issue is in need of a fix, or do you just class it
as an annoyance?

Could the local agent at least continue delivering to the rest of the
non-broken recipients (problem - then everybody would get the
repeats, but at least everybody gets the mail in the first place)?

We almost need to distinguish between "simple" forwards and complex
aliases, where simple would be done directly in the local agent (risk
of duplicate delivery) and complex would be pushed back into the queue
(performance cost). I'm racking my mind to think of a way to draw the
line between the two.

Maybe it would be enough to deliver direct when an alias only has one
right hand side, or there was a program or include on the right hand
side, with other cases treated as a forward/requeue?
