Thanks for all the replies.
The answer is changing sendmail.cf by
adding DMaptix.com
And I'll upgrade sendmail to latest version later as suggested.

We are using sendmail-8.8.3 on SunOS 4.1.4 server.
When we send email, our address is user@mail.aptix.com or
user@extsvr.aptix.com
How do I modify sendmail.cf so the address will only show domainname
$user@aptix.com without hostname?
