80 Postfix Domain Name Not Found Update

Postfix domain name not found. Here is mine that works well. The only postfix config file that omv writes is etc postfix main cf. Earlier setting tried to query server1 to the external dns and failed so email bounced.

I need to fix it asap. How to solve host or domain name not found. Searcing for the cause i suspect it caused by them having reject unknown sender domain enabled in their postfix config.

But before the reload be sure your nameservers in etc resolv conf are correct. Telnet ip port 25 doesn t work. Ask question asked 5 years ago.

A simple postfix reload fixed the problem. It happened to me once after etc resolv conf change that postfix somehow get stuck. Compare it to yours.

Now as we are using fqdn dns query would give the correct result and. Apt get postfix dpkg reconfigure postfix apt get mailutils mail user host domain mailq or more var log mail log i either get connection timed out or no route to host or host not found try again some errors are from trying to email external servers which might be prevented because isp s block it i think. I am using raspbian and the postfix version 2 9 6 service seems to be automatically run when i boot but if i want to send a mail the email stays in the queue.

Host name and domain name is correctly set mxtoolbox complains for reverse dns. From the internet i found that postfix tries to resolve the myorigin name by going through dns query. If it was a config issue wouldn t it affect all omv systems ability to resolve a domain name.
