Hi More fooling around with postfix,
Using in main.cf smtpd_sender_restrictions = reject_unknown_reverse_client_hostname did not do what I expected: from the /var/log/mail/info file: Jul 12 09:12:48 rap postfix/smtpd[6597]: NOQUEUE: reject: RCPT from unknown[92.45.179.70]: 450 4.7.1 Client host rejected: cannot find your reverse hostname , [92.45.179.70]; from=<eononagenar...@ajsquare.com> to=<k...@rap.rap.dk> proto=ESMTP helo=<asy70.asy179.tellcom.com.tr> I then used: host 92.45.179.70 Which gave: 70.179.45.92.in-addr.arpa domain name pointer asy70.asy179.tellcom.com.tr And this means that there is a PTR RR. Can it be something about postfix not set up to do reverse name lookups? best regards keld
