Run "/usr/libexec/sendmail/sendmail -bt -d 0.1" and it should show a  
section called "SYSTEM IDENTITY" which should indicate what it is  
seeing for your "short domain name", "subdomain name", etc.  That  
should indicate what you need to change, but if nothing else works,  
adjust this in /etc/mail/sendmail.cf:

# my official domain name
# ... define this only if sendmail cannot automatically determine your  
domain
#Dj$w.Foo.COM
