Hi, I'm using an ISPconfig 2 where a domain ist hosted for http. Let's name it Server A for customer A and domain A. The mx-record is pointing to another server (Server B). This is not a problem since someone external sends to this domain. But when another client that is hosted on server A tries to send an Email to customer A, the Server A feels responsible, but he's not, because Server B is. How can I tell Server A that every Email for domain A shall be forwarded to Server B? THX a lot Edit: Sorry, I chose the wrong Forum. Could someone please move my Thread?
