I'm not familiar with AD, but on the Postfix side can use reject_unverified_recipient to query a destination server if it would accept mail for a recipient. Postfix maintains a cache for positive and negative reject_unverified_recipient results. https://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient Wietse _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
