Problems sending eMail


We have realized that our server is not sending emails. This is a big issue. We have others after migrating our server.

In the queue this is the error we get:

Host or domain name not found. Name service error for type=MX: Host not found, try again

We guess is something wit the DNS but we can't find the problem.

I would appreciate some help.




Sounds like your system is having trouble resolving DNS .. is one of your domains, or one you are trying to send to?

If it is one you are sending to, what is the output of the following command on your system :


it should report the IP and mail servers for that domain.
