Need help with a strange mail/domain problem!

[Thomas Beutler]

Hi everyone!

I'm a total stranger to the Unix world... too long have I dwelled in the
Windows area, and now I'm searching
for new horizons and worlds to explore... the Unix world. I looked around
and found FreeBSD interesting
enough to install... and here I am with a strange problem:

I installed FreeBSD 5.0-Release and got the system running. So far - so
good.
Second task: Install bind and get the DNS running. So far - so good - at
least I think so.

Third task was to get my email work... and now the problems begins.

I own the domain beutler.se, and my computers name is visthusboden.
The server accepts incoming mail all right - no problems there... BUT...
...whatever I do, all outgoing mail get the address
user at visthusboden.beutler.se instead of user at beutler.se

What am I doing wrong?

I've checked and tripple-checked every file in /etc/namedb/ and everything
looks fine (no missing dots or
some simple problem like that) and I've really read this through in the
FreeBSD manual... and still... ???

I'm at whits end here folks... please help me out!

Kind Regards
/Thomas
