same here.
How to fix?

you would need to manually edit your zone file which are reported in the error
All zone files are in /var/named/ folder, you can compare it with others.

Hi mostly related :
So right after an install, i created the package, the user, the DB , a domain and go to add email account. All website is working, accessing by the domain. When I open
Roundcube mail : I can received email. But I cannot sending out to hotmail or gmail.

 For using an external mail service, like Zohomail do i just change 1 line as :

I go at DNS Functions /List DNS Zones/ Select the domain name and click edit record.

 The record show as :

Mail     /  0   / IN   / CNAME   /  TheExternalMailDomain


 Without having to put DKIM.. and rdns that i don't know how ?

Many thanks

Hi, you need to change MX record,
yourdomain.      30      IN      MX      5      yoursever.

change with:

yourdomain.      10      IN      MX      5      mx.zoho.com.
yourdomain.      20      IN      MX      5      mx2.zoho.com.
