Message IDs
by Philip Colmer Oct. 16, 2021

Oct. 16, 2021

I'm posting here first (rather than submitting a bug report on GitLab) because I'm not sure if I've overlooked a configuration setting. We're running the latest versions of the various Mailman 3 packages on Ubuntu 20.04, using Postfix as the MTA. Mailman 3 has been configured to apply DMARC mitigation unconditionally, replacing From: with the list address. The situation we're seeing is that if person A sends an email from a Google account to Mailman 3 and receives the (modified) post back from Mailman 3, the message ID is not being changed. Google's behaviour then is not to show that message to the user because it thinks it is the same message that the user sent out. Since Mailman 3 is modifying the message, it ought to have a different message ID. Is that a configuration setting I've missed or a bug, please? Thank you. Regards Philip

SQL Schema request
by Ruth Ivimey-Cook Oct. 16, 2021

Oct. 16, 2021

Folks, I needed to migrate my previously-sqlite based mailman core to mariadb, and have more or less managed it, though I feel certain the table schema I ended up with is not what mailman would have created for itself. Is there any way to get a copy of the mysql/mariadb table schema that I can then pour the existing data into (i.e. I don't want to reinitialise the db)? Thanks, Ruth -- Software Manager & Engineer Tel: 01223 414180 Blog: http://www.ivimey.org/blog LinkedIn: http://uk.linkedin.com/in/ruthivimeycook/

Trying to set up mailman3 on my mail server
by Shawn Heisey Oct. 15, 2021

Oct. 15, 2021

I'm having a lot of trouble with trying to set up mailman3 on my mail server. It's on an AWS instance, running Ubuntu 20.04 LTS. All software is installed from Ubuntu packages. Mailman version is 3.2.2. The problem I am trying to troubleshoot first is how this can be happening: Oct 14 11:27:26 2021 (2341) ACCEPT: <f36e1ed0-9d25-b661-9c94-4ce999f6d5fd(a)elyograg.org> Oct 14 11:27:27 2021 (2344) Cannot connect to SMTP server 127.0.0.1 on port 25 From the shell, I can "telnet localhost 25" successfully, even as the "list" user. Apparmor is disabled. The UFW firewall is enabled, which allows all traffic on the loopback interface. I disabled ipv6 at the kernel level, but had the same problem with ipv6 enabled, so I don't think ipv6 is related at all. I do not see any connections in the postfix log that correspond to the mailman connection error. From a fresh install of mailman, I created two mailing lists. Once upon a time I had those lists active on a Debian 6 machine running mailman 2.1.13 ... I copied the mailing list config from that machine over and used the "import21" facility to import the configuration into the new mailman3 install. That worked without error and I can see the lists and their members with the "mailman" command. I found instructions for integration with postfix, and added the required three config lines to the postfix config. When I try to send a message to the list, I get what I pasted above in the mailman log. I think that means the postfix integration is working, and is forwarding to mailman. I'm hoping somebody can give me some pointers, and if more information is needed for troubleshooting, let me know what is needed. I'm also having trouble with the web UI ... I thought I had found what to do with Apache, but it's having problems and I do not know what to do so it works. The UI is not super important right now, I'd like to get the lists working first. I first tried to get help on the IRC channel, but that appears to be a dead end. I did give it several hours. Thanks, Shawn

Trying to get mailman3 in docker working with external Mysql database
by bob B Oct. 11, 2021

Oct. 11, 2021

Our database group has created the database with (charset=utf8mb4&use_unicode=1) and a user For my docker-compose.yaml I will only have two container sections mailman-core mailman-web which should have these database variables set under each: -DATABASE_URL=mysql+pymysql://[database_user]:[database_password]@[database.server.ip]:[databseport]/[database_name] - DATABASE_TYPE=mysql - DATABASE_CLASS=mailman.database.mysql.MySQLDatabase Are these all correct? in looking at documentation should it be: DATABASE_URL=mysql+pymysql://[database_user]:[database_password]@[database.server.ip]:[databseport]/[database_name]?charset=utf8mb4&use_unicode=1 Or/and should I also use? DATABASE_URL=mysql+pymysql://.... or DATABASE_URL=mysql://... or DATABASE_URL=pymysql://.... Do I have to install pymysql? or is it installed in the dock images? Do I have to run any other commands on the database first? I assume mailman does everything it needs for the database at first launch?

Activation of HyperKitty archive on Debian
by Eggert Ehmke Oct. 4, 2021

Oct. 4, 2021

Is there a straighforward instruction how to make it work on Debian Bullseye? All instructions I find seem to use the git method, and also there are warnings to mix the methods. Installing mailman3 with Debian methods was straightforward, and worked out of the box. Though it purged my mailman2 installation without warning, that was a hard blow. Had to reinstall all my lists in a night session. Also lost the old archives and can't get the new get running.

Broken web interface Ubuntu 20.04
by Simon Brown Oct. 1, 2021

Oct. 1, 2021

Hello, Whilst I wasn't looking something has broken the web interface to mailman on our list server. On the list index page I get the Postorius header, but no list index, instead a Page not found error. Curiously the Postorius header is also broken, the links point to https://host/mailman/(postorius/lists|hyperkitty) not https://host/mailman3/(postorius/lists|hyperkitty) like it should I've poked around and I can't find any useful errors and I don't know exactly when this happened, but I think it was this week. Mailman itself is running happily underneath. Any suggestions as to what might have gone wrong? Simon P.S. Hopefully I've got the right list this time. -- Simon Brown System Engineer EISCAT Scientific Association P. O. Box 812, SE-981 28 Kiruna, Sweden simon.brown(a)eiscat.se
