I have a single exchange 2003 server. I have 3 different domains that need to send email from this server. Company.com Companytwo.com Companythree.com The way i have it is simply with aliases. Every users has all 3 addresses. I simply set each users Primary email address in the properties page. So one user might look like this smtp bob.tomato@comapany.com SMTP bob.tomato@comapanytwo.com smtp bob.tomato@comapanythree.com X400 c=us......blah blah and another users would look like this SMTP larry.cu@comapany.com smtp larry.cu@comapanytwo.com smtp larry.cu@comapanythree.com X400 c=us......blah blah Is this the correct way to setup multiple domains on one exchange system? Thanks Ben

Hi, That is one (correct) way. Another way would be to use recipient policies and have the desired addresses assigned automatically. Leif
