Greetings. So, we are getting closer to rolling out some hyperkitty goodness for production. Now we need to determine how we want to manage the rollout from a techincal angle. First, some history/description of how our current lists work: HTTP/HTTPS: Requests to admin.fedoraproject.org/mailman are proxied from any proxy to collab03 (located at osuosl). lists.fedoraproject.org is just a A record directly pointing to collab03, so requests go direct to it. SMTP: incoming: lists.fedoraproject.org has MX for our 3 smtp-mm machines. They are located in 3 places around the globe. They accept emails for lists and relay them to collab03. If collab03 is down or they can't reach it, they simply queue and wait. outgoing: collab03 relays everything to bastion01. bastion01 sends the emails out. This I think is to make sure all *.fedoraproject.org emails come from the same ip address and don't shift around. (Note that the path for non lists emails is a bit different). So, my hyperkitty migration plan: 1 Figure out how to get http and smtp to it with NO disruption of existing urls and emails. 2 Setup test list and do some testing. 3 Once that looks good, move on to migrating a list over (this list perhaps :) 4 Then, migrate a bunch more opt-in. 5 Then, set a sunset date on the old setup and migrate the rest. Options for item 1: 1) Setup forwards on collab03 for any lists going to mm3 and setup httpd redirects for admin.fedoraproject.org/mailman/*listname* and lists.fedoraproject.org/mailman/*listname*. This means a lot of monkeying with the config and apache redirects are sometimes very fragile. 2. Make a new 'mailman3.fedoraproject.org' hostname, set smtp-mm's to accept for it and send on to mailman01/02. Setup proxies to proxy mailman3 into mailman01/02. This makes it nice and seperate, but means list names change? 3) Hybrid: Setup mailman3.fedoraproject.org for the web interface only, use forwards for the smtp side. This means list names could stay the same, but web interface is different. Might confuse people where a list web interface is. 4) Your brilliant plan here. ;) Thoughts? kevin
