We have a domain, abc.org.
We have an external website http://test.abc.org. People can send and receive emails to / from that site (it has a built-in email server).
If the user from our domain sends an email to [email protected], the emails are sent fine.
if they reply to an email sent from [email protected], the addresses are modified to [email protected] and they get a NDR if they try to reply to it.
So far, the solution is to manually change the address they want to send to.
What should I do so that they can just hit “reply” and the addresses are correct? Would the creation of a subdomain fix the problem?
