SMTP Protocol: Define a non-existing "Relayer" preventing ALL emails be delivered.sikhanegi wrote: ↑2023-05-01 17:17Hello,
We are trying to set up a separate mail server for a group of employees who don't access our Exchange server. I'm using hmailserver for the separate server and the users will live on one of our domains called "abc.com". Our main domain, used by all other employees on Exchange is "xyz.com".
what I've been tasked to do is allow this new email server is to allow the users on it (abc.com) to send and receive email to and from "xyz.com" only. No other external domain mail will be allowed.
Is there a way to do this?
SMTP Protocol - Routes: define a route for domain xyz.com to be delivered to your exchange. That's the exception to the above "Relayer"
