problem with multiple email account in centos web panel

Hi, I have a problem with CentOS Web Panel and the email server, I just get it to work because of DKIM (DomainKeys Identified Mail) 2 domains are not thrown at me I have it this way configured. Each one in your file. The fact is that I do not see how to set up several email accounts and they work well in CentOS Web Panel, how could I do it ?, greetings and thanks ..

You didn't give much infor where you host the DNS. Add those DKIM there and remove the old one

my dns host is digitalocean and I have the server with its IP in a CentOS 7.x with CentOS Web Panel and I have it configured as I show in the image each domain is a separate file.

if DKIM DNS is not working  then it is DNS host issue.

well maybe I explained badly, the problem I have can see here really the problem is that I only signed with a domain that is placed in mydomain in the main.cf file and the file structure I have it here.

I wish someone could help me because I have been with this problem for some time and I can't fix it and I really need it.
To mount postfix and opendkim I have used everything preferably from the control panel centos web panel.

if DKIM DNS is not working  then it is DNS host issue.

FYI if I rebuild mailserver from cwp with ONLY DKIM box checked, this is what the results are:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
You have a troubles with yum. Fix it before install!
And this:

Code: [Select]

Failed to restart opendkim.service: Unit not found.
I did not check the box for CLAMAV.

 Ok and as it is fixed because I do not give the solution to the problem, I have been looking for a solution for a long time I need to be able to send emails with the domain that agrees with the server, if not, so I want a VPS.
Besides, where are you seeing that?
He tried many possible solutions searching the Internet and I have not found any that works, the domain of farewellsexclusivas.com works perfectly are the other 2 domains that fail in the DKIM signature, why fails is what I would like to know? and if Amavisd does not use it, it is interfering with the signature in some way.

Besides, where are you seeing that?

Dashboard-Email-Mailserver Manager

ok,
could you tell me that I have badly configured or that I have not configured to operate the opendkim in the 2 domains that does not work, added the domains as I explain in the gitlab I have it as it is there.
