I have a couple of different businesses, there domains are different. How can i set up a E2k on w2k with multiple domains so i am avle to set up individual outlook clients to send/receive from one domain or another ie. blank@mydomain1.com or blank@mydomain2.com. so when xyz sends out an email from mydomain1.com all the email shows coming from that domain and incoming goes to the same, and vice versa with the 2nd domain name. This might be a stupid question, but we have recently migrated from 5.5 to e2k.
