Hello,

problem:
1. a webshop working on a keyhelp server with domain webshopdomain.com
2. webshop notify the webshop owner about new orders to sales@webshopdomain.com
3. keyhelp server try to deliver email locally
4. webshop owner using email on other mailserver

how to force keyhelp to try to resolve the real MX for the domain?

Code: Select all

Hello,

disable the mailservices for this domain.

Edit the domain via the pencil symbol and uncheck the option "Email domain"


If you use external DNS for the domain then disable the DNS services for this domain, too.
