Hi,
I just watched an IP address fail to be correctly resolved back to
the A record. I could resolve the IP with the the same DNS on the same
server myself.
These connection from a server is recorded by postfix as unknown for
212.89.81.105, yet an nslookup on this IP resolves back to the correct
address:-
Non-authoritative answer:
105.81.89.212.in-addr.arpa name = smtp.academicjobseu.com.
Feb 15 13:06:26 logout postfix/smtpd[111]: warning: 212.89.81.105:

Feb 15 13:06:34 logout postfix/smtpd[111]: disconnect from
unknown[212.89.81.105]
Is there something that I missed in the postfix configuration?
Best wishes, S
