I know that this isn't quite the correct forum for this question, but I thought I would ask anyways. I am running sendmail on one server for 2 different domains. For company A the mail gets sent and received correctly For company B the mail gets received correctly. But for company B when the mail is send directly from the server box (logged on as company_b_user) the from address shows correctly i.e. company_b_user@xxxxxxxxxxxxx When that user sends mail from his outlook at home and relays thru the server the from address shows up as company_b_user@xxxxxxxxxxxx I am using the virtusertable, genericstable and the generics-domains. Anyone know how to rewrite the from address correctly, the from email address in MS outlook shows company_b_user@xxxxxxxxxxxx Any help would be appreciated. TIA
