The old IP/name could be cached at FreeBSD. >=20 I thought it sounded like dns too. But I was under the impression that only= a reverse lookup was used against the Server name sent by postfix. I have = specifically requested a ptr record in the arpa zone=2C and I can run a res= olveip successfully here. Is my info wrong? Is the lookup done against more than just the Server name= set in main.cf?
