Proxy error.
by Mark London 18 Jun '23

18 Jun '23

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 17 Jun '23

17 Jun '23

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 16 Jun '23

16 Jun '23

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

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 15 Jun '23

15 Jun '23

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

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] 14 Jun '23

14 Jun '23

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]>".

Re: Why is a mailing list not sending the moderator subscribe or post notifications?
by Mark London 14 Jun '23

Argh, that is it! Thanks!!!! Admin immed notify YesNo Should the list moderators get immediate notice of new requests, as well as daily notices about collected ones? List moderators (and list administrators) are sent daily reminders of requests pending approval, like subscriptions to a moderated list, or postings that are being held for one reason or another. Setting this option causes notices to be sent immediately on the arrival of new requests as well.

Why is a mailing list not sending the moderator subscribe or post notifications?
by Mark London 14 Jun '23

14 Jun '23

Hi - I migrated from mailman 2 to mailman 3. All but one list is working correctly. That list is not sending the moderator any emails. It appears to configured exactly like the other lists. I.e. subscription requests and moderated users posts don't generate any emails to the moderator (me). I tried changing moderator email addresses, and everything else I could think of, but nothing worked. What can I do to debug this problem? This list is much larger than any of my other lists. And has a huge archive. I doubt that is a factor, but I’ll mention it anyway. Also, how do I run the command to remind me of awaiting moderation requests, so that I can run it hourly? In case this can’t be fixed quickly. As an aside, I had some mailman 2 lists that had no moderators. I could swear that for them, that the owners would get moderated requests. Am I hallucinating? I can't check the old server any longer. Thanks. – Mark
