Zimbra - can anyone help me get my zimbra to receive external emails?
I "think" that I have set up everything I need to get my zimbra server to receive emails but it doesn't!
I get this error when trying to send to a users email "553 553 sorry, that domain isn't in my list of allowed rcpthosts"
I have checked the mx record and that points to the right ip address for the server. I have tried sending to a non existent user on the server and I get a different error so I am assuming it is getting so far but I cannot get any further.
Can anyone who has zimbra up and running help at all?
