thanks for your input. Bill: deliver is just a symlink to dovecot-lda Stephan: I don't know, and and it even does not work when I use deliver -f "postmaster@ourdomain.internal" - I get the same error message.
A part of the mail I got when using 2.2.23: Return-Path: <MAILER-DAEMON> Delivered-To: user1@ourdomain.internal Received: from localhost (localhost [127.0.0.1]) by hosting.ourdomain.internal (Postfix) with ESMTP id 8E985424C7 for <user1@ourdomain.internal>; Thu, 25 Jan 2018 12:36:59 +0100 (CET) Content-Type: multipart/report; report-type=delivery-status; That's strange.
