Whats maybe wrong here?
whats in /etc/mailname
or the nullmailer equivalent?
last I remember, you had to use a valid hostname to send mail.
so it just had to resolve, it didn't have to resolve to you.
if it didn't resolve to you, the bounces would go astray, but worst case, you needed a valid hostname in /etc/mailname.
i think there is a file for nullmailer that lets you identify yourself to the mail server.
