I.e. Gmail applies a DMARC policy of p=reject to mail From: gmail.com even though it's published DMARC policy is p=none. You need to apply DMARC mitigations to this mail. Unfortunately, this requires setting DMARC Mitigate unconditionally to Yes. Mailman 2.1 has a feature to apply DMARC mitigation to messages From: specific domains regardless of any domain specific DMARC Policy. Unfortunately this hasn't been implemented in Mailman 3 yet. I just filed https://gitlab.com/mailman/mailman/-/issues/1084 for that. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Where does sender postorius@ come from?
by Jens Günther June 19, 2023

June 19, 2023

I just realized, that mails for registering an account and/or resetting ones password are obviously sent from postorius@SERVE_FROM_DOMAIN. Why are they not sent from MAILMAN_ADMIN_EMAIL? The problem is: - an account is trying to register with a mailaddress from a HostEurope-server - HostEurope-Servers are doing Sender-Callouts (bad practise :-D) to verify that a mailaccount exists - mail is then bouncing, b/c those are not answered (shoud I?): status=bounced (host [80.237.138.5] said: 550-Sender verification is required but failed. - bounce then can't be processed, since mailaccount does not exist :-D status=bounced (mail for SERVE_FROM_DOMAIN loops back to myself) Am I missing something are shouldn't it be better to send those mails from MAILMAN_ADMIN_EMAIL? (I don't want to mess with these sender callouts or change anything, HostEurope has been a little bit of a pain in the ... with mailinglists and not much help at all). Thanks in advance, Jens.

Proxy error.
by Mark London June 18, 2023

June 18, 2023

My server has several aliases. And Chrome's cookies sometimes get messed up because of it. Several users get a proxy error when trying to connect to the mailman website. One person just fixed it by clearling cookies, although this is not a great solution. Error log says "You may need to add 'psfcmail2.psfc.mit.edu' to ALLOWED_HOSTS". But it is already there in /etc/mailman/settings.py Or should it go elsewhere? Thanks. - Mark Chrome: Proxy Error The proxy server received an invalid response from an upstream server.

mailman3 auto-disabling of subscriptions
by Mike Wertheim June 17, 2023

June 17, 2023

I'm running an email list on mailman3. My users are getting inundated by messages saying that their subscriptions have been disabled due to their bounce score exceeding the mailing list's bounce_score_threshold. But there is nothing wrong with these users' email accounts. They are all perfectly fine. Apparently the issue is somehow related to spam. Whenever I (as admin) get these emails, I just unsubscribe the user and then re-subscribe them. But also, the user gets confused and emails me about it, which unnecessarily takes up their time and mine. The relevant list settings are currently... bounce score threshold: 5 bounce info stale after: 7d bounce disabled warning interval: 7d bounce disable warnings: 5 What's the best way to fix this? I'm considering reducing "bounce info stale after" to "2d" and/or increasing "bounce disabled warning interval" to "90d".

Postorius -owner messages
by ssehi＠nebraska.edu June 16, 2023

June 16, 2023

I manage a number of lists for non-technical users that are considered owners of their own lists. Some of them have expressed that they would like to emulate some other mailing list services' "Quiet" owners for people that need to be able to access the list settings for administrative reconciliation as well as a fallback, but want to leave subscription requests or approval of messages to others that are more involved in the day-to-day management. They'd like to disable owner delivery for themselves, and I'd like to not make the change for them using the shell every time I get one of their requests. We have a Postorius front end set up and working, but it doesn't appear that disabling delivery using the List-based preferences in the Postorius interface stops those Owner communications. Is there a way to allow users to disable that natively in Postorius? Thanks, Sam

I have two users who are getting a proxy error message when they try to connect her our mailman server: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request Reason: Error reading from remote server Apache/2.4.52 (Ubuntu) Server at lists.psfc.mit.edu Has anybody else in an errorlike this before? One person manage to get around this by going in incognito mode on the browser. Does that make any sense?

unrequested unsubscription
by Mike Wertheim June 15, 2023

June 15, 2023

I have a Mailman 3 email list, running on Mailman 3.3.3 on Debian 11. A few of the list members are reporting that they received Email Address Unsubscription Confirmation emails, but claim that they never requested to be unsubscribed. (All are Gmail users. but they might be coincidental, since most list members are Gmail users.) Has anyone seen this behavior before? Any ideas on what might be happening?

SSO

June 15, 2023

Is it possible to set up SSO so that once users (owners,moderators) set up an account in Postorius on the mailman3 server we have created , they can authenticate against Azure to login instead of the password for the local account Postorius created?

How to remove a message with an invalid Message-Id?
by McGuire, Tommy M. (MSFC-IS61)[EAST2] June 14, 2023

June 14, 2023

I have a fun problem: apparently a message sent to a mailing list has an invalid Message-Id (I think), which is causing the message parse to fail while attempting to archive the message. Unfortunately, the message seems to be trapped somewhere and resulting in error logging every few minutes. Is there any way to find and remove the message? Literally, the only thing I've been able to find out about it is that the Message-Id contains the text "[83c48dddbea7492e873224a5ae1c04be-JFBVALKQOJXWILKNK4YVA7CBPJ2XEZKEMV3E64DTPRCW2YLJNR6EK6DPKNWXI4A=(a)microsoft.com]>".
