Sendmail doesn't think that it is supposed to be accepting mail
for bawel.net, but when it tries to send it to the "right" place, it
discovers that the only logical place to send the mail is back to the
computer that is already handling the mail (in other words, sendmail
looks up the MX records for the domain and discovers it is about to pass
the message on to itself!). This confuses sendmail.

Let sendmail know that it is supposed to be accepting mail for bawel.net.
Add a line with "bawel.net" to /etc/sendmail.cw.
