Hi Mark - First of all, thanks very much for getting back to me. Secondly, there's something I realised I didn't mention in the bug report, which may count as a 'free pass' for you to handball the problem back - I'm running Mailman 2.1.20 on Ubuntu 16, not Mailman 3. I've put off upgrading because I understand the move to v3 is a major architectural change, and I have a lot of legacy lists and users to worry about.
Anyway - in the course of experimenting with the content filter settings, I tried a number of options. Finding a tip online from someone else who identified different subtypes of multipart, I tried adding multipart (without any subtype) to pass_mime_types. When that didn't work, I tried multipart* to see if there was such a thing as a wildcard (I think I tried multipart% and multipart/* as well), but I didn't try adding text/plain. So, I've just done that - no dice. When I send to the list from the Gmail app on an Android phone with the pass_mime_types field completely clear, mail gets to the list. With the mime type set to your three options, nothing gets through and nothing appears in the vette log - which is consistent with the message having been so gutted by the filtering process that there was nothing left to pass or reject. I've attached an example of a message that gets through to the list with pass_mime_types cleared, and is lost with the filtering turned on. In case the act of attaching it loses anything, the headers as received at the list were: Return-Path: <[email protected]> X-Original-To: [email protected] Delivered-To: [email protected] Received: by mail.jeremygregson.com (Postfix, from userid 500) id 52C2F4021C; Mon, 27 Aug 2018 13:47:18 +1000 (AEST) Received: from mail.lochac.sca.org (vmx20482.hosting24.com.au [163.53.249.53]) by mail.jeremygregson.com (Postfix) with ESMTP id 36B0440215 for <[email protected]>; Mon, 27 Aug 2018 13:47:18 +1000 (AEST) Received: by mail.lochac.sca.org (Postfix, from userid 500) id E453E481FD5; Mon, 27 Aug 2018 13:48:12 +1000 (AEST) X-Spam-Checker-Version: SpamAssassin 3.4.1 (2015-04-28) on vmx20482.hosting24.com.au X-Spam-Level: X-Spam-Status: No, score=-0.0 required=3.2 tests=BAYES_00,HTML_MESSAGE, MAILING_LIST_MULTI,MISSING_MIMEOLE,RDNS_DYNAMIC,SPF_HELO_PASS,URIBL_BLOCKED autolearn=no autolearn_force=no version=3.4.1 Received: from mail.lochac.sca.org (localhost [IPv6:::1]) by mail.lochac.sca.org (Postfix) with ESMTP id 8B2F4481F89 for <[email protected]>; Mon, 27 Aug 2018 13:48:12 +1000 (AEST) X-Original-To: [email protected] Delivered-To: [email protected] Received: by mail.lochac.sca.org (Postfix, from userid 500) id 9BA8F481FD5; Mon, 27 Aug 2018 13:48:10 +1000 (AEST) Received: from mail.jeremygregson.com (203-217-61-26.perm.iinet.net.au [203.217.61.26]) by mail.lochac.sca.org (Postfix) with ESMTP id 36E9A481F89 for <[email protected]>; Mon, 27 Aug 2018 13:48:10 +1000 (AEST) Received: by mail.jeremygregson.com (Postfix, from userid 500) id E964A4021C; Mon, 27 Aug 2018 13:47:13 +1000 (AEST) Received: from [10.183.142.121] (unknown [1.144.228.246]) by mail.jeremygregson.com (Postfix) with ESMTPSA id 87B3940215 for <[email protected]>; Mon, 27 Aug 2018 13:47:13 +1000 (AEST) Date: Mon, 27 Aug 2018 13:48:04 +1000 Message-ID: <[email protected]> X-Android-Message-ID: <[email protected]> To: [email protected] Importance: Normal X-Priority: 3 X-MSMail-Priority: Normal MIME-Version: 1.0 Subject: [Selenetest] Test subject X-BeenThere: [email protected] X-Mailman-Version: 2.1.20 Precedence: list List-Id: <selenetest.lochac.sca.org> List-Unsubscribe: <https://lochac.sca.org/mailman/options/selenetest>, <mailto:[email protected]?subject=unsubscribe> List-Archive: <http://lochac.sca.org/pipermail/selenetest/> List-Post: <mailto:[email protected]> List-Help: <mailto:[email protected]?subject=help> List-Subscribe: <https://lochac.sca.org/mailman/listinfo/selenetest>, <mailto:[email protected]?subject=subscribe> From: Nico via Selenetest <[email protected]> Reply-To: Nico <[email protected]> Content-Type: multipart/mixed; boundary="===============8988888446188673456==" Errors-To: [email protected] Sender: "Selenetest" <[email protected]> Any further suggestions will be appreciated.
