How can I tell IspConfig, that there are additional mailman3 configuration entries at main.conf. Just now they will be overridden by ispconfig_update.sh with reconfiguration option. Do I use /usr/local/ispconfig/server/conf-custom/install/main.cf? Must I write the additional entry, for example: Code: virtual_alias_maps = hash:/var/lib/mailman3/data/virtual-mailman or the complete item Code: virtual_alias_maps = hash:/var/lib/mailman3/data/virtual-mailman, proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, proxy:mysql:/etc/postfix/mysql-virtual_email2email.cf or the complete main.cf.
ISPConfig does not support Mailman 3, but I guess he wants to install it manually. You must copy the template of the service you like to customize from install/tpl/ folder of the ISPConfig tar.gz file to the folder /usr/local/ispconfig/server/conf-custom/install/ and then alter the template to match your custom config.
@etron770 if you can share how you make mailman3 works on your ISPConfig server will be nice. I did attempt to transition to it few times but failed so I stop because I can't focus much to make it works due to real life things. If you can share your steps, others may benefit from them, and further help to make them better and available for all ISPConfig users.
I found a couple of hints until i solved it. Sorry I am not allowed to post clickable links. I used the automatic installation howtoforge.com/ispconfig-autoinstall-debian-ubuntu/ I added a local Mysql user with root priviliges but no password. You will be asked for a root user, but there is no possibility to enter a password. At this stage, you must use your local root user without a password. Just now, I do not know if it is possible to remove it later. If you choose MySQL, you will need about 6Gb memory. If not, you will get lost connections between mailman and MySQL. I preferred MySQL. I moved the database to an additional pure MySQL server. Attention, you will need two MySQL databases predefined, a user f.e mailman3 and mailman3-web. And it is a little handwork if you want to go back from the default sqlight3 database to MySQL in a production installation. Then I installed mailman3-full the hints I followed additional linuxcloudvps.com/blog/how-to-install-mailman3-on-debian-11/ appuals.com/no-module-named-mysqldb/ serverfault.com/questions/733304/getting-mailman3-to-play-nicely-with-postfix-and-dovecot#733374 Hopefully, I remembered all the things.
