I need to see if it's possible to change the From address on email that is sent from our AIX 5.3 server. We have an application that sends out email and the from address is "username@<servername>.domainname.com". Is there a way in sendmail to change it so the from address is "email@example.com". Also is their a way control the "username" part of the address? If the process is run by "root" then the email come from "root@<servername>.domainname.com".
