The message is a bit missleading. You can't just add a TrustedUser to 
sendmail and run this test. You would have to change all privileges.... 
It's absolutely ok to check the daemon as root.

The Parse1 ruleset considers brad at bradcan.homeliniux.com as a local 
machine's user (Class $=w in sendmail). Therefore it strips the domain.

You can check $=w like this:

sendmail -C sendmail.cf -bt
 > $=w
localhost
[127.0.0.1]
dell2600-1.bradcan.homelinux.com
[...]
 >/quit

Look for bradcan.homelinux.com

Do you have an entry for bradcan.homelinux.com in /etc/hosts? Then you 
can simply delete it.
