You didn't say when you'd be calling this ACL, nor why you'd
only be verifying bounces. Not generating bounces yourself
is also worthy, which means validating recipients of nonbounce
messages; using the routers and possibly transports to do the
validation (which is what "verify" does) is one way.
I assume the recipients you are validating are non-local
to this box, since you specify callout. But you could be
confused about the intent of recipient verification.
