Davide and I spent most of today getting Mailman3 up and running.
https://lists2.socallinuxexpo.org/mailman3/ is up with CentOS 9 and Mailman3.
All the goodies are - I think - there, including archives.
I've made a test list called scale-test you all can subscribe to if you like and start playing around.
Various notes: * I have *not* yet tweaked all of it's settings to match our preferences, but I will soon. * I have also not imported existing lists or archives from mailman2, though that is possible. That's why I said 'initial' testing. I want to get a bit more familiar with the knobs and whistles. * The superuser account is in 1Password in the "Tech - online services" vault, which the Infra team and Ilan should have access to. * If you would like to _own_ a list, I can make a list, and assign it to you, but you'll need to register first. Anyone can register, it gives you no special permission though. * You do NOT need to register to join a list. If you later register, you'll then be able to manage your preferences through though the website. * I have *NOT* set up phplist or mailgun, as I'm rather hoping we'll move off of them, but if we decide not to, I'll setup both. * The standard / redirect still goes to an invalid mailman2 URL, I know. Just go to /mailman3 for now.
