With /etc/aliases, use the owner- prefix to redirect bounces for a
specific recipient address.
Quote from Posfix aliases(5):
In addition, when an alias exists for owner-name, delivery diagnostics
are directed to that address, instead of to the originator of the mes-
sage. This is typically used to direct delivery errors to the main-
tainer of a mailing list, [...]
There is no equivalent feature for virtual aliases. This would require
an additional recipient attribute for the recipient-specific envelope
sender address, plus support in the queue manager to sort delivery
requests by that envelope sender and destination. I wish I had thought
of that 19 years ago, as it could have simplified some other code.
