why owner mails rerouted to list
by Tamas HOLCZER Oct. 23, 2019

Oct. 23, 2019

Hi All, we have moved to Mailman3 from Mailman2 recently, and have a quite strange problem: Every message sent to owners is forwarded to the lists instead of the owner's mail address. So for example if a non-member sends a message to MYLIST(a)MYDOMAIN.COM, then a notification appears on MYLIST (and all members receive it, the message also appears in the archive) instead of sending it to the private address of the owner set on the web interface. I found no obvious error either in mailman.log, smtp.log or the MTA's logs. This problem can cause a storm of mails as per default the owner is not allowed to send a message to a member-only list so each notifications generates a new notification. This storm is mitigated temporarily by accepting everything from the owner in a non-member setting, but it is only a workaround. I want mails sent to MYLIST-owner(a)MYDOMAIN.COM to be forwarded to the real owner instead of the list. The same is true for MYLIST-admin(a)MYDOMAIN.COM, and probably for the other administrative addresses. We are using GNU Mailman 3.2.1 (La Villa Strangiato) from the Debian Buster repo. As MTA we use exim4 (running on the same machine as Mailman), and have Amavisd on a separate machine for spam filtering. How can I test what happens to mails sent to the owner inside Mailman? Any help or tips on debugging this issue would be highly appreciated. Best regards, Tamas Here is an anonymized header for such a message: From MYLIST-bounces(a)MYDOMAIN.COM Mon Oct 21 21:13:59 2019 Return-path: <MYLIST-bounces(a)MYDOMAIN.COM> Envelope-to: MYADDRESS(a)MYDOMAIN.COM Delivery-date: Mon, 21 Oct 2019 21:13:59 +0200 Received: from [SPAMFILTER] (helo=localhost) by MAILSERVER.MYDOMAIN.COM with esmtp (Exim 4.92) (envelope-from <MYLIST-bounces(a)MYDOMAIN.COM>) id 1iMd7u-0007pv-VR; Mon, 21 Oct 2019 21:13:59 +0200 X-Virus-Scanned: by amavis-dc Received: from MAILSERVER.MYDOMAIN.COM ([MAILSERVER-LOCAL-IP]) by localhost (spamfilter.MYDOMAIN.COM [SPAMFILTER]) (amavisd-new, port 10023) with ESMTP id Pe6CPG7d_0VR; Mon, 21 Oct 2019 21:13:57 +0200 (CEST) Received: from MAILSERVER2.MYDOMAIN.COM ([MAILSERVER-PUBLIC-IP] helo=MAILSERVER.MYDOMAIN.COM) by MAILSERVER.MYDOMAIN.COM with esmtp (Exim 4.92) (envelope-from <MYLIST-bounces(a)MYDOMAIN.COM>) id 1iMd7t-0007pn-Mu; Mon, 21 Oct 2019 21:13:57 +0200 Received: from MAILSERVER2.MYDOMAIN.COM ([MAILSERVER-PUBLIC-IP] helo=MAILSERVER.MYDOMAIN.COM) by MAILSERVER.MYDOMAIN.COM with esmtp (Exim 4.92) (envelope-from <MYLIST-bounces(a)MYDOMAIN.COM>) id 1iMd7r-0007pR-JZ for MYLIST-owner(a)MYDOMAIN.COM; Mon, 21 Oct 2019 21:13:55 +0200 From: MYLIST-owner(a)MYDOMAIN.COM To: MYLIST-owner(a)MYDOMAIN.COM MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="===============1338746665924884909==" Message-ID: <157168523467.30989.13607822853875106726(a)MAILSERVER.MYDOMAIN.COM> Date: Mon, 21 Oct 2019 21:13:54 +0200 Precedence: bulk X-Mailman-Version: 3.2.1 Message-ID-Hash: UWYSMZDJO3ZXNBKY6GE6AS6FBLCZL6BG X-Message-ID-Hash: UWYSMZDJO3ZXNBKY6GE6AS6FBLCZL6BG X-MailFrom: MYLIST-bounces(a)MYDOMAIN.COM X-Mailman-Rule-Hits: nonmember-moderation X-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation Subject: [MYLIST] MYLIST(a)MYDOMAIN.COM post from ... requires approval List-Id: Name of the List <MYLIST.MYDOMAIN.COM> Archived-At: <https://MYDOMAIN.COM/hyperkitty/list/MYLIST@MYDOMAIN.COM/message/UWYSMZDJO3…> List-Archive: <https://MYDOMAIN.COM/hyperkitty/list/MYLIST@MYDOMAIN.COM/> List-Help: <mailto:MYLIST-request@MYDOMAIN.COM?subject=help> List-Post: <mailto:MYLIST@MYDOMAIN.COM> List-Subscribe: <mailto:MYLIST-join@MYDOMAIN.COM> List-Unsubscribe: <mailto:MYLIST-leave@MYDOMAIN.COM> --===============1338746665924884909== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit As list administrator, your authorization is requested for the following mailing list posting: List: MYLIST(a)MYDOMAIN.COM From: ...

To what extent can mailman 3 handle images and html?
by Paul Arenson Oct. 23, 2019

Oct. 23, 2019

Hi The other day I attempted to send a message from my mail client (Apple computer, Mail program, html--well, what they call Rich Text). While a user was able to send a message previously that contained an image, I was unsuccessful. As well, links were weird. LINKS ===== Because My wordpress often has a Japanese URL and they can become very long, I tried both the URL as is and embedded (made a clickable html link). URL === So while I typed https://www.tokyoprogressive.org/journalist-ito-shiori-sues-alleged-rapis.... It came out double as https://www.tokyoprogressive.org/journalist-ito-shiori-sues-alleged-rapis... <https://www.tokyoprogressive.org/journalist-ito-shiori-sues-alleged-rapis... (The full link was truncated with ... at the end, and the link appeared twice with the second instance preceded by "">") The embedded one did not come out embedded buy showed the text like this: Alternate link: 多摩川河川敷に男性の遺体、増水した川に流されたか <https://www.tokyoprogressive.org/%e5%a4%9a%e6%91%a9%e5%b7%9d%e6%b2%b3%e5%... QUESTION 1: Is there a preferred way to write links, or will there always be problems with the mail clients? (Even the web archive shows this problem though): https://list.tokyoprogressive.org/hyperkitty/list/discuss@list.tokyoprogres… See the top item Homeless man drowns in river during Typhoon and what I mean. IMAGE No image appears though one was added inline. And, as I said, a user was previously able to add one. I do not know how she did it. I also posted it to my web site instead of the newsletter for unrelated reasons. But there was an image (Originally got a warning the message was held because the attachment or something). So are there guidelines one whether/how to attach an image so that it makes it? Thanks

How do I configure mailman to use a unix socket for lmtp connections? Setting [mta] incoming: mailman.mta.null.NullMTA lmtp_host: /path/to/socket does not work. Mailman still tries to create a TCP socket.

Receiving 8bit-clean mail
by Alyssa Ross Oct. 20, 2019

Oct. 20, 2019

A subscriber to a mailing list I administer has been sending 8bit UTF-8 encoded mail, with no further quoted-printable / base64 / etc. encoding. This is handled fine by my MTA and MUA, but Mailman seems to have trouble with it. When mail is sent out from Mailman, the « character is replaced by ??. Is this a bug, or is there just a configuration option or something I need to set? I couldn't find anything in the documentation.

Converting discussion list to read-only list (settings)
by Paul Arenson Oct. 17, 2019

Oct. 17, 2019

I have found that my users in the discussion list are creating their own topics rather than using the existing ones, so decided to make it a read-only list and use WordPress moderated comments. Since I do not have the original settings for READ ONLY (this is a hosted version), I want to make sure that these are correct. Can someone comment. Thanks MOST IMPORTANT—> What setting makes it a discussion list as opposed to read only? ALTER MESSAGES ----------------------- Filter content Now YES Collapse Alternatives Now yes Convert html to plain text Now NO Anonymous NOW YES Include RFC2369 headers Now Yes Include the list post header Now Yes Reply Goes to List Now No munging Pipeline Default DMARC MITIFGATIONS ----------------------- Replace From with list address DMARC mitigate unconditionally Now NO MESSAGE ACCEPTANCE ----------------------- Require Explicit Destination Yes Administrivia YES Default action to take when a member posts to the list Hold for moderation Default action to take when a member posts to the list Hold for moderation OTHER? ------------- Thanks Paul Arenson

max_delivery_threads
by Sven Buesing Oct. 16, 2019

Oct. 16, 2019

Hi, we are currently running mailman version 3.3.0. We want to enable max_delivery_threads - we want to send personalized mails (To: ), and we hope that threading would speed things up - but it seems this option has no functionality despite being documented in the schema.cfg. Threading is compiled into python: >>> import sysconfig >>> print(sysconfig.get_config_vars('WITH_THREAD')) [1] Am I doing anything wrong or is the documentation simply wrong? This ist the mta-section of the mailman.cfg. [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver max_delivery_threads: 20 max_recipients: 500 lmtp_host: 127.0.0.1 lmtp_port: 8024 smtp_host: 127.0.0.1 smtp_port: 25 configuration: python:mailman.config.postfix Regards, Sven

Tune Mail Delivery
by Brian Carpenter Oct. 14, 2019

Oct. 14, 2019

Some ISPs require outgoing delivery to not exceed a certain threshold. With Mailman 2, we used the following: SMTP_MAX_RCPTS SMTP_MAX_SESSIONS_PER_CONNECTION Does Mailman 3 have an equivalent to the above 2 settings? Thank, Brian
