what is from with this picture?

I have been trying to install ubuntu as a desktop while maintaining
freebsd as my server.  A few days ago mail was working.  But, checking
my /var/logs/ on my ubuntu I see:


Sep 28 09:10:46 newtao postfix/smtp[8064]: 73A14E81F39:
to=<freebsd at edvax.de>, relay=mx01.schlund.de[212.227.15.169]:25,

'newtao.thought.org' (misconfigured dns?) (in reply to RCPT TO command))

By default, postfix was installed on my ubuntu desktop.  I am not
familiar with it.  I would =like= it to be sending mail to my server
without the $HOST name instead of $HOST.$DOMAIN name.  I know there are
a bunch of us who use this kind of setup: FreeBSD for server things and
some version of linux as a desktop.

Really, this looks like a postfix blunder.  How do I tell postfix to
rewrite th e outgoing address without the hostname?

PS: FWIW: I still have the oldtao alive and well.  It's just old and
overdue for replacement.
