If, as seems to be implied, the target system rejects nonexistant recipients inline, then a simple 'verify=recipient/callout' in the right part of your RCPT ACL will prevent you receiving mail for invalid recipients on that target system. You can configure the behaviour at this point - whether you blackhole them or reject them is up to you - rejecting is generally better because a non-zero percentage will be genuine mis-typed addresses which should be notified to the sender.
