Postfix configuration

[cristian_arg]

Hi.
A question, after install centos web panel, you must perform some configuration with respect to postfix?
Since the configuration of postfix shows:
The variable mydomain = yourdomain.com
                  myhostname = name VM

And if I had to modify it as I do it if I have two domains?

Sorry for the translation.

Thanks!

Perform this query because I have a problem with mails, back with the message
"THIS IS A WARNING ONLY. YOU DO NOT NEED TO RESEND YOUR MESSAGE"

[Administrator]

this should be only your hostname and domain of the host no other domains!

For mail server logs try to rebuild the mail server and check the logs of it.

So what could be the problem for much of the mails remain in the queue?
Any idea?

Thansks!
