I installed Postifx on OpenLeap 42.3 openSuse. Firstly, I had issue that domain with AAAA record was not found and I defined in main.cf that inet_protocols=ipv4 After that I tried to send mail but neither mail was received nor I I have got in /var/spool/postofix/defer report that message is deferred with reason why is deferred. Please advise how to make it report me on error message if message is not being sent.
Thanks Vedran
