I'll explain my situation:
I have a Qmail server with the domain abc.com, and, I installed the new server Zimbra with same domain (abc.com).
I migrated some users to my zimbra server.
When I send an email to my domain, that email is delivery in my Qmail server and my Qmail make a copy and redirect to my zimbra. This work fine.
I'd like that when someone send an email to my domina (abc.com) using zimbra, the email be delivered in my qmail server (not local, only zimbra).
What I need to do? Is this possible?
