How To Install Mailman 3 on Debian 10 (Complete Guide)
by Brian Carpenter March 14, 2021

March 14, 2021

I have finished my how-to install Mailman 3 on Debian 10 completed to the point where you can use it to get a fully functional Mailman 3 environment up and running. This is a comprehensive guide that walks you through installing EVERYTHING (currently!) that Mailman 3 needs to run. It also makes updating Mailman 3/Postorius/Hyperkitty very easy. I have not added the update directions yet but will very soon. I also plan on adding a section on setting up DKIM and Xapian with Mailman 3. I hope this helps those who wish to get a Mailman 3 server up and running quickly and brings a sense of sanity to the confusion regarding the various documentation out there concerning the installation of Mailman 3/Postorius/Hyperkitty. I intend to add a How-to for Ubuntu 20 at some point. Without further ado: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 I am sure the above guide can use improvements. Feel free to contact me off-list to point out mistakes/improvements, etc. -- Brian Carpenter Harmonylists.com Emwd.com

hooking up mailman and sendmail
by John Covici March 14, 2021

March 14, 2021

Hi. So, I have sendmail as my mta and I want mailman to use it. So far, I have a local delivery agent able to send on port 8024. So, what do I have to tell mailman to use sendmail and listen on port 8024 and to send on port 25? Thanks in advance for any suggestions. -- Your life is like a penny. You're going to lose it.

problems installing mailman3 under gentoo and upgrading mailman2 to mailman3
by John Covici March 14, 2021

March 14, 2021

Hi. I am having a great deal of difficulty installing mailman3 using gentoo and sendmail. Also, I want to upgrade my old mailman2 data to mailman3. What I have done so far is to install the mailman3 packages from my repository and got this: django-mailman3 version 1.3.4, mailmanclient version 3.3.1, mailman version 3.3.2 (apparently the core), postorius version 1.3.3 and hyperkitty version 1.3.3. I also have mariadb and postgresql already installed. Now trying to read your documentation, it seems it wants me to reinstall some packages using pip in the home directory of the mailman user in a python virtual environment, that was the first thing. But I would like to avoid multiple package managers wherever possible -- gentoo is already a lot of maintainance without dealing with pip's maintainance. The binaries also seem to be different from my gentoo packages. So, how do I proceed with getting mailman3 up and working, configuring the database, configs, etc and I guess after doing that upgrading mailman2 and getting sendmail to interface properly with mailman3? Thanks in advance for any suggestions. -- Your life is like a penny. You're going to lose it. The question is: How do you spend it? John Covici wb2una covici(a)ccs.covici.com

Hi, I have this error message repeating endlessly into the mailman-web logs. The related list is an open one on which we receive spam sometimes. I understand these emails can me malformed and cause this error. How to deal with them? They can't stay forever at the hyperkitty door. Thanks in advance, _g.

Attachments in digests mails
by Eric Broens March 12, 2021

March 12, 2021

Hi, subscribers that prefer to receive digests, are receiving attachments as encoded characters in the message body. This makes digests almost unreadable, see an extract of an example below. Is there a way to make sure the attachments are send as attachments in the digest mails?

Posterious membership listing for non-owner/moderators?
by Duane Raymond March 11, 2021

March 11, 2021

Hi, I'm configuring my new mailman3 lists and one option I wish to use is a membership listing (which list members can opt-in/out of via their preferences). The only problem is, via the web interface (Posterious / Hyperkitty) I can't find that listing when logged in as an ordinary member. Am I missing something or is this not built in yet? I have my test list setting under List Identity -> Members List Visibility set to "Only mailinglist members", but all I can find in terms of members is the side-listing of posters to the list/thread. (as usual before asking the question I explored a lot and searched the archives/documentation). Cheers, Duane

Setting for archiving multi email domains?
by Duane Raymond March 11, 2021

March 11, 2021

Hi again, I have a Debian-postfix-postgres-nginx-Hyperkitty-Postorius setup with a primary domain (e.g. primarydomain.com) and several 'secondary' domains used for email lists (e.g. emaillistA.com and emaillistB.com). When sending emails to a list using the primarydomain.com address, the email is received, sent to subscribers and archived properly. But when it is sent to one of the secondary domains like tes(a)emaillistA.com - the email doesn't seem to be sent and isn't archived - despite it being set to be. What I've tried so far (after searching these archives and looking at the documentation) is to: 1) Adding emaillistA.com and emaillistB.com to the MAILMAN_ARCHIVER_FROM setting in the settings_local.py file (and then restart mailman) 2) Adding emaillistA.com and emaillistB.com to the mydestination setting in the postfix main.cf file (and the restarting postfix). ...I even tried adding to /etc/hosts 127.0.0.1 emaillistA.com and 127.0.0.1 emaillistB.com but removed it as it didn't seem appropriate there. Does anyone have any hits of what else I need to configure to get it working for these 'secondary' email domains? Cheers, Duane

Backups & disaster recovery of mailman3
by David Partain March 8, 2021

March 8, 2021

Hi, So now I have a running mailman3 installation. Whew... Is there documentation of things like thorough backups and disaster recovery? I haven't yet found it. Backups: Obviously, I understand that I need to have datbase (mysql, in my case) dumps, and I'll have file system backups onto something that our IT folks will backup. Is there more I should think of? Disaster recovery: So, let's say my server (which is cloud-y) gets trashed and I need to get mailman back on a new server. Is this process described somewhere? My kind thanks to you all for listening :) Cheers, David

Importing issue from mailman2 to mailman3
by David Partain March 7, 2021

March 7, 2021

Hi, I'm in the process of moving 1400-ish lists from a very old mailman2 installation to an installation on Ubuntu 18.04 with the version of mailman3 packaged for that distro. (Yes, that was a mistake, but I'm committed at this point.) I'm doing this import as per: sudo -u list mailman import21 somelist@one-of-the-domains<mailto:somelist@one-of-the-domains> /tmp/lists/somelist/config.pck where /tmp/lists includes all of the list configs from the old installation. Most of it's going fine, as best I can see. However, I get exceptions on some lists that look like this: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/sqlalchemy/engine/base.py", line 1182, in _execute_context context) File "/usr/lib/python3/dist-packages/sqlalchemy/engine/default.py", line 470, in do_execute cursor.execute(statement, parameters) File "/usr/local/lib/python3.6/dist-packages/pymysql/cursors.py", line 163, in execute result = self._query(query) File "/usr/local/lib/python3.6/dist-packages/pymysql/cursors.py", line 321, in _query conn.query(q) File "/usr/local/lib/python3.6/dist-packages/pymysql/connections.py", line 505, in query self._affected_rows = self._read_query_result(unbuffered=unbuffered) File "/usr/local/lib/python3.6/dist-packages/pymysql/connections.py", line 724, in _read_query_result result.read() File "/usr/local/lib/python3.6/dist-packages/pymysql/connections.py", line 1069, in read first_packet = self.connection._read_packet() File "/usr/local/lib/python3.6/dist-packages/pymysql/connections.py", line 676, in _read_packet packet.raise_for_error() File "/usr/local/lib/python3.6/dist-packages/pymysql/protocol.py", line 223, in raise_for_error err.raise_mysql_exception(self._data) File "/usr/local/lib/python3.6/dist-packages/pymysql/err.py", line 107, in raise_mysql_exception raise errorclass(errno, errval) pymysql.err.DataError: (1406, "Data too long for column 'info' at row 1") My assumption is that what's in the "Info" field on the old mailman2 config is simply too long. Is that correct? In that case, I suppose the right thing is to (1) edit each one, reducing the size, which'll create a new config.pck, (2) pull it over to the new machine, and (3) run the import again. Seem reasonable? Cheers, David
