Hi, I posted this message before, but did not get any answers, so I am trying again. I am a totally newbe to E2K server and have just installed the 2000 SmallBusinessServer with E2K standard version. I am trying to set up several domains on one server. I have done the following: -Set up DNS with ex1.abc.com as a domain controller on server EX1 -Set up MX record ex1.abc.com to point to @xyz.com. Set up Mailbox store for EX1 -In Recipien Policy/Default Policy set up @xyz.com as smtp -In Default SMTP Virtual Server / Advanced Delivery / Fully-qualified Domain Name: ex1.abc.com (Tested and OK) -POP3 is set up with the correct IP address. -In Active Directory I have set up a user with bjorn@xxxxxxx as smtp e-mail address in both Exchange General and E-mail Addresses Then the big question is? What have I left out or what have I done wrong since this is not working? When sending to the address bjorn@xxxxxxx, I get the message in return saying that no such address exists. I have gone trough all the articles about setting up SMTP vitual servers on Microsoft site, but it obviousley does not cover all my problems. I will greatly appreciate any help in this matter. Regards Bjorn
