Finding a mailman3 installation description that works
by ralf.wiegand＠tena-sda.org April 1, 2020

April 1, 2020

WE are currently using mailman2. I have the task to setup and install a maiman3 server. Postfix is installed and working. Can anybody point me to a link where the actual installation is described using RHEL 7 or RHEL 8. This will be a hardened DISA compliant server, so I am trying to avoid installing compilers and tools that are not part of the standard RHEL 7 repos. Thank You, Best regards, Ralf Wiegand

Mailman3 moving to new server, not able to establish SMTP connection
by Andrew Hodgson March 28, 2020

March 28, 2020

Hi, Whilst we are all stuck in doors I have started a project to move Mailman3 from a Docker installation to a new server using a Python venv. Old server was Debian Jessie and the new one is Buster. Using Exim with stock config. Everything seems to be going ok but mail isn't delivering (cannot connect to SMTP server). I have /opt/mailman which I did chown -R list:list mailman.cfg has following MTA settings: [mta] incoming: mailman.mta.exim4.LMTP configuration: python:mailman.config.exim4 I wrote a Systemd unit which starts Mailman from the venv and started up Mailman once I got Postgres sorted so it would create the necessary files in the var directory structure. One thing I noticed and had to fix is that it doesn't creat the directories for existing lists, and the Exim config examples out there check for the existance of those directories to identify whether the address exists. I created those anyway and set ownership perms as before. Once I fixed that I sent a test message to the owner address and that routed correctly and the headers indicated the message was sent back to localhost by Mailman. However I can't get it to route a list message, here is a log showing the start of the Mailman master processes and me sending a test message from Outlook (so incoming mail is routing ok): Mar 28 16:03:20 2020 (21877) Master started Mar 28 16:03:32 2020 (21889) lmtp runner started.

This is a dualstack machine and I was wondering whether we had any IPV6 issues (I had an issue with Gunicorn and Nginx routing traffic due to this earlier that I had to sort), but as owner addresses are working I don't know what is different on that. Any suggestions? Thanks. Andrew.

421 - Too many sessions from source IP

March 27, 2020

My new MM3 server is receiving these errors from cox.net: "(delivery temporarily suspended: host cxr.mx.a.cloudfilter.net[34.212.80.54] refused to talk to me: 421 cxr-ibgw-6004a.stratus.cloudmark.com cmsmtp too many sessions from 213.125.4.246.

AUP#CXCNCT) " The link gives just this: 421 - [too many sessions from <source IP>] The sending IP address has exceeded the five maximum concurrent connection limit. Configure your sending server to establish no more than five concurrent connections. 1. Is that a legitimate excuse to refuse passing on emails or is cox.net too stingy? 2. Is that a setting we need to change in Mailman somewhere? Or should this be handled in some Postfix setting? Yours, Allan

Things I miss about mailman2
by Quanah Gibson-Mount March 24, 2020

March 24, 2020

Now that we are on mailman3, I'm finding things that were really useful in mailman2 are completely missing in mailman3, which seems odd, since they in particular affect the ability of list moderators to do their job well. a) When a post was made to a moderated list in mailman2, I would get an email that included a LINK to the held email. Now I just get a canned email saying I need to go to the dashboard, blah blah. Why was this link removed? It was extremely useful and now I have to jump through extra hoops. b) When a post is made to a moderated list in mailman2, when I went to the page to approve/deny/discard, there was additionally an option to remove the moderated flag from the user for all future emails. This option no longer exists. This was EXTREMELY useful, as we force all new members of the list to be moderated for a time while we evaluate the quality of their postings. Now I have to go manually track down the user and their settings. Unnecessary extra hoops to jump through c) When a post is made to a moderated list, one of the options when selecting REJECT was it allowed me to set a custom message when rejecting the email. This was extremely useful. For example today, someone emailed our bug tracking list directly instead of filing a bug. In the past, I would have added a note to them about what they should do (in this case, I would have told them to send their email to our community technical discussion list). Now I can no longer do that, I can only reject it or discard it. Why was this removed? --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Xapian alternatives
by Andrew Bernard March 24, 2020

March 24, 2020

Are there alternative search engines to Xapian that can be used for Mailman 3? I have come to understand that Xapian development stalled in the v2.0 attempt.

Finding a user to delete them
by Quanah Gibson-Mount March 17, 2020

March 17, 2020

Due to a bug in mailman3, I have an incorrect user that's been created via github auth that has no confirmed email address yet. I've been poking around the user manager documentation (why is there no UI for user management???), and after adding in bits that are missing from the official documentation (<https://mailman.readthedocs.io/en/latest/src/mailman/model/docs/usermanager…> is missing "from mailman.testing.documentation import dump_list" despite using dump_list repeatedly in its examples) I can't find the user. I have the confirmation email mailman3 sent out, that tells me the username mailman3 created for the incorrect account is "quanah98", but the user manager documentation doesn't detail how to find a user by their username, only their email. And apparently if the email hasn't been confirmed (and I *do not* want it confirmed), you can't find them by email. Suggestions on how to track down this user so I can delete them would be much appreciated.

Add old email address
by Quanah Gibson-Mount March 14, 2020

March 14, 2020

We've recently migrated our project's email lists from mailman2 to mailman3. Given the project has been around for a few decades, many people have used different email addresesses over the years, some of which they no longer have access to. However, it would be useful to still be able to associate those emails with a given account. Is there a way that I can do this as an administrator of the mailman3 system? Thanks, Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
