Hi list, Since i have upgraded ASSP from 1.98(13056) to 1.99(13107),i have noticed that we cannot receive Message Disposition Notification anymore (rfc3798), they are blocked Now every MDN messages are blocked by ASSP Backscatter Detection because of MSG-SIG check failure. In the blocked emails header we can see :
In-Reply-To: <BD786772F903534781150FCAB4A79A5C01733CF7@ourmailserver> Auto-Submitted: auto-replied (vacation) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable X-Assp-Version: 1.99(13107) on ASSP.nospam X-Assp-ispip: 62.73.4.63 X-Assp-Re-Red: Subject: Auto: X-Assp-SenderBase: country:FR; organization:Mail Essentials Project; domain:orange.fr X-Assp-Score: 50 (MSGID-sig check failed for bouncing sender <>) X-Assp-Redlisted: Yes (Subject: Auto:) X-Assp-Envelope-From: X-Assp-Intended-For: alexandre.rayn...@sallanches.fr X-Assp-ID: ASSP.nospam m-36765-00094 X-Assp-Spam: YES X-Assp-Spam-Found: MSGID-sig check failed for bouncing sender <> X-Assp-Message-Totalscore: 50 Return-Path: <> X-OriginalArrivalTime: 04 May 2013 09:15:40.0764 (UTC) FILETIME=[F2A019C0:01CE48A7] When using version 1.98(13056) and mdn messages were not blocked, mdn messages headers looked like this : In-Reply-To: <assp.0829efbdb5.BD786772F903534781150FCAB4A79A5C0173394E@ourmailserver> Auto-Submitted: auto-replied (vacation) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable X-Assp-SenderBase: country:FR; organization:Mail Essentials Project; domain:orange.fr X-Assp-Redlisted: Yes (Auto-Submitted:) X-Assp-Envelope-From: X-Assp-Intended-For: alexandre.rayn...@sallanches.fr X-Assp-Passing: Valid MSGID signature X-Assp-ID: ASSP.nospam (m-36705-00977) X-Assp-Version: 1.98(13056) Return-Path: <> X-OriginalArrivalTime: 27 Apr 2013 10:05:04.0475 (UTC) FILETIME=[B03E42B0:01CE432E] I have discovered the apparent reason as we can see In-Reply-To section of header : OUTGOING EMAIL ARE NO LONGER SIGNED and this is what causing problem to receive mdn messages (null sender) that are naturally blocked by Backscatter Detection. Every single mail we send is no longer signed............. Should we revert to 1.98 version or maybe there is a configuration change in 1.99 version preventing outgoing messages to be signed? Thanks for any help.
