Or if you're running postfix...

in /etc/postfix/main.cf uncomment this line:

#myorigin = $myhostname

so it looks like this:

myorigin = $mydomain

Then restart postfix.  That will affect all mail from the machine so 
instead of getting mail from root at blah.mydomain.com, it will be 
root at mydomain.com.  It's been 7 or 8 years since I've fondled a sendmail 
config so I don't recall off the top of my head how to translate that 
into an m4-ism.

Hope that helps.
