Find a smtp server to send out emails
by Leon Jan. 15, 2025

Jan. 15, 2025

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman3. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. -- Best wishes, Leon

by Mark Jan. 6, 2025

Jan. 6, 2025

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

Cache mailman3

Is there a way to delete the mailman3 cache? It's because it gives us this error and we think it's because of the cache.

Re: mail stuck in "out" queue

SIGINT killed the process allright, but it didn't auto-respawn. I ended up spawning it with: /usr/local/bin/python /usr/local/bin/runner --runner=out:0:1 -C /etc/mailman.cfg but soon realized it doesn't go to background nicely so I've nohup'ed it in the end. but it did solve my problem. -- Sr System and DevOps Engineer SoM IRT

How to Increase outgoing mail volume for Mailman 3
by Brian Carpenter Dec. 9, 2024

Dec. 9, 2024

Hello everyone, We had a new client come on board that brought a list that had the largest out-going mail volume that I have ever dealt with. So I did what any sane server administrator would do that is running Mailman 3: I ran to Mark Sapiro for help! Here is what the Sage of all things Mailman counseled me to do: 1. Disabled VERP delivery. VERP can help improve mail delivery by delivering 1 message per SMTP transaction (I think I got that right). Using VERP is counter-productive as it can seriously delay outgoing mail delivery for a high-volume list. So you can use something like the following in the MTA section of your mailman.cfg: [mta] verp_confirmations: no verp_personalized_deliveries: no verp_delivery_interval: 0 2. I configured Mailman 3 to run 4 outgoing runners. The default is 1. This action was the game changer. It allows Mailman to handle 4 incoming messages at a time instead of 1. My client's incoming list volume was high enough where it was overwhelming the single outgoing runner. Here is what I added to the mailman.cfg file: [runner.out] instances: 4 Doing this step immediately solved the backlog in var/queue/out. 3. If you start up with a new server for a list that is high volume then keep an eye out for Proofpoint and Vade Security as they will block your new IP address quicker than Mark Sapiro can say "This is a bug. See <some Gitlab.com url>" Mark, thank you! -- Brian Carpenter Harmonylists.com Emwd.com

Aborted connection message in log in every 5 minutes
by zoltan＠circle-interactive.co.uk Dec. 3, 2024

Hi Everyone, we have mailman 3.3.8 venv test installation which in general works fine however our mysql error log is filled up with messages below because they are so frequent. 2023-02-24 0:31:30 199567 [Warning] Aborted connection 199567 to db: 'mailman' user: 'mailman' host: 'localhost' (Got an error reading communication packets) 2023-02-24 0:36:30 201063 [Warning] Aborted connection 201063 to db: 'mailman' user: 'mailman' host: 'localhost' (Got an error reading communication packets) 2023-02-24 0:41:31 202559 [Warning] Aborted connection 202559 to db: 'mailman' user: 'mailman' host: 'localhost' (Got an error reading communication packets) 2023-02-24 0:46:31 204056 [Warning] Aborted connection 204056 to db: 'mailman' user: 'mailman' host: 'localhost' (Got an error reading communication packets) As suggested here https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… I tried to correlate with error logs and /opt/mailman/web/logs/mailmanweb.log shows some hyperkitty.lib.utils Failed to update the fulltext index: (2002, "Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (111)" /opt/mailman/web/logs/uwsgi-error.log Message: OperationalError(2013, "Lost connection to MySQL server at 'handshake: reading initial communication packet', sy stem error: 104") but they have not such frequency so unsure if they are related. Thanks for the suggestions

Moving existing lists to a new domain
by Jeremy Stanley Nov. 21, 2024

Nov. 21, 2024

I've moved lists and archives between domains in Mailman 2.1 and Pipermail, but not yet with Mailman 3 and Hyperkitty. I have a working multi-domain deployment, and one of the organizations using it is working on changing their domain name. Forwarding incoming messages at the MTA and setting up redirects on the Web server are simple enough, but internally within MM3/Django reside the bits I'm less certain about. Since all the lists for the given domain will be moving to the same unused new domain on the existing server, and can move at the same time, I suppose this could be done through (offline if necessary) backend database update queries. Is there anything outside the DB which would need updating or regenerating for this too? Is this how others have tackled similar tasks in the past, or is it recommended to export/import lists one at a time out of one domain and into another? Any tips are greatly appreciated! -- Jeremy Stanley

Migrating from old V2 server to new V3 server. Questions.
by jkoral＠luc.edu Nov. 14, 2024

Nov. 14, 2024

We have figured out how to migrate from one server to another, but after removing the list from the old server, the e-mails are still trying to go there. Is there something that needs to be done in mailman so that the e-mail list will hit the new server instead? Does it just take time? Thank you, Joe Koral

Timeout error on anonymous subscribe
by vogt＠spamcop.net Oct. 25, 2024

Oct. 25, 2024

Hi, I am running a mailman 3.3.9 server (pip installation). It's working fine so far. However, I have problems setting a template. I set a '[list:user:action:subscribe]' template for a list with some simple text like "test1234". When someone wants to subscribe on the list page without creating an account, it takes five seconds until "HTTPSConnectionPool(host='lists.example.org', port=443): Read timed out. (read timeout=5)" appears on the page. The mail address has been added pending confirmation but no mail gets send. mailman.log shows just exceptions about the timeout itself: Sep 09 15:01:45 2024 (2070549) deque: do_confirm_verify Traceback (most recent call last): File "/opt/mailman/venv/lib64/python3.11/site-packages/urllib3/connectionpool.py", line 536, in _make_request response = conn.getresponse() ^^^^^^^^^^^^^^^^^^ ... requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='lists.dkrz.de', port=443): Read timed out. (read timeout=5) [09/Sep/2024:15:01:45 +0200] "POST /3.1/members HTTP/1.1" 400 132 "-" "GNU Mailman REST client v3.3.5" The access log suggests that getting the template took 5s: ==> /opt/mailman/mm/var/logs/access.log <== 127.0.0.1 - - [09/Sep/2024:13:01:45 +0000] "GET /mailman3/api/templates/list/community.lists.example.org/list:user:action:subscribe HTTP/1.1" 200 8 "-" "python-requests/2.32.3" Running curl on that url returns immediately $ curl -v 'http://localhost:8000/mailman3/api/templates/list/community.lists.example.o…' I have captured the network traffic on localhost interface lo and I can see that the request is sent through the tcp connection and acknowledged. Then 5 seconds later the server (port 8000) sends a push data with the response and closes the connection with FIN. The data exchanged on the connection looks like this: GET /mailman3/api/templates/list/community.lists.example.org/list:user:action:subscribe HTTP/1.1 Host: lists.example.org User-Agent: python-requests/2.32.3 Accept-Encoding: gzip, deflate Accept: */* X-Forwarded-Proto: https X-Forwarded-For: 2001:638:1234:1224::111 X-Forwarded-Host: lists.example.org X-Forwarded-Server: lists.example.org Connection: Keep-Alive HTTP/1.1 200 OK Server: gunicorn Date: Mon, 09 Sep 2024 13:01:45 GMT Connection: close Content-Type: text/plain; charset=utf-8 X-Content-Type-Options: nosniff Referrer-Policy: same-origin Cross-Origin-Opener-Policy: same-origin X-Frame-Options: DENY Vary: Accept-Language, Cookie Content-Language: en Content-Length: 8 test1234 The timestamp 13:01:45 is the time of the timeout. The request started five seconds before that. It looks to me as if the connection/keepalive handling is not working properly or the server isn't pushing the response immediately, but it gets buffered until the 5s timeout. Occassionally, I have capture a requests, where the client side would send a FIN to the server and only then the server would send the http response with the final packets. Does anyone have an idea how I can fix this? Thanks, Gerald
