It's not a DNS issue, it's "sendmail".

What it's currently doing is correct - by default, it uses your fully
qualified hostname for the Sender address -- it doesn't know that
"user at beutler.se" will work also - so, you need to tell sendmail of this fact:

You can do this with the "massquerading" feature of sendmail.

See:

and more generally: http://www.sendmail.org/m4/readme.html
