So our mailman got stuck again, but I did follow your advise.

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 09 Dec '24

09 Dec '24

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

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

Clearing webserver cache - Nginx

I am having an ugly-looking https://mm3-lists.kictanet.or.ke/archives/ page because of cached content: ``` 2024/08/05 17:00:31 [error] 694#694: *9562 open() "/opt/mailman/mm/static/CACHE/css/output.6dab123e4897.css" failed (2: No such file or directory), client: 172.70.111.39, server: mm3-lists.kictanet.or.ke, request: "GET /static/CACHE/css/output.6dab123e4897.css HTTP/2.0", host: " mm3-lists.kictanet.or.ke", referrer: " https://mm3-lists.kictanet.or.ke/archives/" 2024/08/05 17:00:31 [error] 694#694: *9564 open() "/opt/mailman/mm/static/CACHE/css/output.158acc288604.css" failed (2: No such file or directory), client: 162.158.159.31, server: mm3-lists.kictanet.or.ke, request: "GET /static/CACHE/css/output.158acc288604.css HTTP/2.0", host: " mm3-lists.kictanet.or.ke", referrer: " https://mm3-lists.kictanet.or.ke/archives/" 2024/08/05 17:00:31 [error] 705#705: *9566 open() "/opt/mailman/mm/static/CACHE/js/output.3aaa7705d68a.js" failed (2: No such file or directory), client: 162.158.63.166, server: mm3-lists.kictanet.or.ke, request: "GET /static/CACHE/js/output.3aaa7705d68a.js HTTP/2.0", host: " mm3-lists.kictanet.or.ke", referrer: " https://mm3-lists.kictanet.or.ke/archives/" ``` That IP address appearing there is not my actual IP, but Cloudflare's, which is acting as proxy for the site. Having cleared MM3-web cache, is there anything else I can easily do (apart from disabling CF proxying) to help deal with the above issue? Or am I barking the wrong tree? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS.

Questions regarding message acceptance
by Pawel Grzywaczewski 19 Sep '24

19 Sep '24

Hello, I have few questions regarding usage of Mailman3: 1) We have list1 and list2 with members. Can we specify that all members of list1 can post messages to list2? We could potentially write a script that would synchronize members of another list to “Accept these non-members” of another list, but with thousands of lists it will be difficult to maintain lists in synchro. So perhaps there is a concept of adding another list to “Accept these non-members” and mailman real-time evaluate membership of another list upon message arrival? 2) In explanation of “Accept these non-members” it’s written: “While non-regexp addresses can be entered here, it is preferred to add the address as a nonmember and set the nonmember's Moderation to Default Processing”. I noticed that if someone posts to a list then he is added automatically to non-members. Which means that next time he will be able to post. My understanding is that it’s better to use the feature “Accept these non-members”. Am I correct? Thank you, Paweł

Disabled by bounce
by Allan Hansen 11 Sep '24

11 Sep '24

Hi all, Apparently Google just started to get very aggressive about DKIM settings. Some hundreds of my subscribers have had their subscriptions disabled because of Google's bounces. I tried to 'Enable' some of them, expecting that their bounce scores would be reset, but when I list the users, the bounce scores are still 5. Please advise. Will enabling them without the bounce score being reset just cause the server to disable them again. Yours, Allan

Recipient address rejected: User unknown in local recipient table
by eyoelz＠gmail.com 11 Sep '24

Hi, I set up mailman3 following the instruction on the mailman3 website. Everything went well until I got to the “Hooking up your mail server” at https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h… . I followed the instructions, but when I try to send an email to one of the lists I created, I get the error below. I have postfix installed on the same server as mailman3. I was wondering if I missed something during the mail server set up process. Relevant parts of my config files are below. Error: Aug 19 15:06:10 xxx-rocky9 postfix/smtpd[153746]: NOQUEUE: reject: RCPT from xxxx.xxxxxx-xx.iphmx.com[xx.x.xx.xxx]: 550 5.1.1 <devops(a)xxx.xxx.edu>: Recipient address rejected: User unknown in local recipient table; from=<xxx(a)xxxx.edu> to=<xxx(a)xx.xx.edu> proto=ESMTP helo=<xx.xx-xx.iphmx.com> mailman.cfg [mta] verp_confirmations: yes verp_personalized_deliveries: yes verp_delivery_interval: 1 incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver lmtp_host: localhost lmtp_port: 8024 smtp_host: localhost smtp_port: 25 configuration: python:mailman.config.postfix recipient_delimiter = + unknown_local_recipient_reject_code = 550 owner_request_special = no mailman/config/postfix.cfg [postfix] postmap_command: /usr/sbin/postmap transport_file_type: hash main.cf smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = xxx.xxx.edu alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases mydestination = $myhostname, mailman, localhost.localdomain, , localhost relayhost = [xx.xx.xx.xx] mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 recipient_delimiter = + inet_interfaces = all inet_protocols = all transport_maps = hash:/opt/mailman/mm/var/data/postfix_lmtp local_recipient_maps =$alias_maps hash:/opt/mailman/mm/var/data/postfix_lmtp relay_domains = hash:/opt/mailman/mm/var/data/postfix_domains Thanks, Eyoel Mengesha

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
