I manage a sendmail box that until now has housed 2 domains. I set the box up as one domain, and then added another. All my users were sending messages from someuser at domain1 when I wanted them to display someuser at domain2. I added MASQUERADE_AS(domain2) into sendmail.mc and all was well. Now, I've added domain 3 and 4 to this box and of course, everything I send is from someuser at domain2 when I want it to come from someuser at domain4. So I've got 10 users who want to be @domain2, 3 who want to be at domain3 and 5 who want to be at domain4. Is there a good way to manage this in Sendmail? I found some docs on using FEATURE(masquarde_envelope) and FEATURE(genericstable) that appears to do what I want this to do, but I'm not 100% sure. Any help would be mucho appreciated. -Brian
