I was under the impression that the system in question was a
multi-tenant system in which some customers wanted delivery to a
single mailbox. And others wanted normal delivery.
Even simpler than REDIRECT or BCC with discard is virtual alias
rewriting:
virtual:
# Entire domain perhaps?
@example.com example-mail@virtual.invalid
# Or recipients one at a time:
us...@example.com example-mail@virtual.invalid
us...@example.com example-mail@virtual.invalid
...
The key question is whether the input criterion is who the mail is
going to, or who the mail is coming from. If suppression of delivery
is for mail *from* particular senders, then REDIRECT is the (only)
way to go.
If you just want to reroute mail *to* particular recipients just
use virtual(5) aliases.
