We host our domain name through server A using an A record pointing to the IP adress.
We use an email adress firstname.lastname@example.org to send out notifications for all people filling out a form and same notice goes to the admin - email@example.com
Our emails are hosted by another server and if I send a notification using a PHP script from CPANEL it just returns my email back to cpanel in the catch-all email adress.
How do I force the system to read the correct MX record and send out all notiifcations to the correct email address hosted on the different server ? I want to achieve this in simple temrs without using complex relays and stuff.
