If your machine tends to choose different hostnames for itself from time 
to time, e.g. because you connect it to different networks, you can 
"fix" it for sendmail by using:

define(`confDOMAIN_NAME', `my.full.host.name')dnl

in your sendmail.mc file.

Also see "MASQUERADING AND RELAYING" in /usr/share/sendmail-cf/README 
and the section on "genericstable" if you want to rewrite outgoing 
usernames as well as domain names.
