AIX 5.3 Sendmail Rewrite From Address

Zone: IBM AIX Unix
Tags: sendmail, aix
I've got a AIX 5.3 Server which has applications that generates out bound email.  This server is not our email server.  The problem is that I need to rewrite the from address.  I have a local user called "myuser" and the outbound email has a from address of "myuser.<servername>@mydomain.com"!  I need it to be "myuser@mydomain.com".  I also need to shield the "root" user from this rewrite (so if an email comes from root I'll know which server it came from).  I cannot seem to get this to work at all.   I don't seem to have a sendmail.mc file only the sendmail.cf file.  I created a genericstable file in /etc/mail with the following command
makemap hash /etc/mail/genericstable < /etc/mail/genericstable

the genericstable contents as follows:
myuser    myuser@mydomain.com
 
and I ran the refresh -s sendmail command but a test shows that nothing changed.

The contents of the sendmail command are as follows:  NOTE: I've changed the actual domain name with "mydomain"!
