Hi, I'm running postfix with spamassassin as a relay (before-queue). The host is connected via OpenVPN. If the tunnel is down mails bounce:
Sep 16 06:08:09 h2786452 postfix-in/smtp[12937]: 194853E04AA: to=<info@>, relay=none, delay=0.01, delays=0.01/0/0.01/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=exchange01 type=AAAA: Host not found) I already created an entry in the hosts file without success. Where can I change the DSN to 4xx and ensure that mails are delivered when the tunnel is up again? helmut@h2786452:~$ postfix.sh -l Getting Instances ... done Instance '-': - - y /etc/postfix Instance 'postfix-in': postfix-in - y /etc/postfix-in Instance 'postfix-out': postfix-out - y /etc/postfix-out helmut@h2786452:~$ Thank you!
