''FEATURE(blacklist_recipients)'' '''


Look up recipients in access database V8.9 and above

The access_db feature (Section 7.5) provides a way to selectively reject envelope sender addresses (and much more). By declaring this blacklist_recipients feature, you enable the access database to also selectively reject envelope recipient addresses. This feature is fully described in Section 7.5.5.
