3B2 nodemane showing up as unix?

[Sysadmin.]

I am working on putting a 3B2 on the net and I'm having a problem.  I've used
the sysadmsh (I think that's what it is called - it's the menu system for the
sysadmin anyway) and I've change the system name to "sysname", for example.
When I log on as a user, "sysname" is displayed.  But when I send mail from
that system to my own system, the return address is "unix!jessea".  This means
that I can't reply correctly because my system doesn't know site "unix".  What
do I need to do to correct this and what is causing it?  Thanx in advance.
