Hello,

I am hosting 3 domains in one server. For headers Return-Path,X-RocketMAILFROM and Received, sendmail puts canonical name of the server with correct usernames. For example if I send and email as user user1, these headers look like user1 at canonicalname.com. For user2 as user2 at canonicalname.com
DNS looks fine and I have in my hosts file the following,

127.0.0.1 localhost localhost.localdomain canonicalname.com
***.**.***.**(server’s ip) domain1.com
***.**.***.** domain2.com
***.**.***.** domain3.com

Any help appreciated.

Thanks.
Alex.
