It looks like postfix doesn't like the sender address "no-reply@efa.*****.local", but I could not find where to change this.Feb 17 18:59:02 efa postfix/smtpd[98611]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 450 4.1.8 <no-reply@efa.*****.local>: Sender address rejected: Domain not found; from=<no-reply@efa.*****.local> to=<maurice@*****.net> proto=ESMTP helo=<localhost>
Any clues?
