With sendmail you can set 'MASQUERADE_AS' in sendmail.mc to the FQDN 
that you would like to have added to unqualified senders.  And if you 
want mail from root to be included in this treatment you have to change 
the default 'EXPOSED_USER' setting which assumes that root mail will be 
kept local or sent to an internal hub where you will want to see the 
real sending host.
