This is complete. If you need to send mail from inside the lab, point your MTA at the relay: relayhost = [relay.front.sepia.ceph.com]:25. It accepts mail from lab networks only and is rate-limited to 60 messages/minute per client. We can now support e-mail aliases in addition to full lists — e.g., infra@ceph.io goes to my team, but it's not a list with members, archives, etc. If you want an alias, please open a tracker ticket. lists.ceph.io itself (lists, archives, and all existing archive URLs) moved with no changes needed on your end. Please let me know if you see anything awry or would like any behaviors changed.

Aside from no longer needing to pay AWS for the service, additional benefits we’ll see from this migration include: * Upgrade from mailman 3.3.1 to 3.3.10. This version includes a task runner that will automatically clean up stuck list subscriptions. This was the main cause for the Web UI hanging and going down over the past few years. * Postgres DB migration from 9.6 to highly available Crunchy DB based on Postgres 16 * Lab-wide SMTP relay * Modern anti-spam stack (postscreen, rspamd) * In-house DKIM signing (mail-tester.com rates us a 8.9/10 score) * Mailing alias (vs. an entire list) support * Proper reverse DNS (helps our spam score) The migration itself shouldn’t take more than 30 minutes. It’s already been tested and everything that can be staged ahead of time is already ready. -- David Galloway Ceph Engineering Labs – Infrastructure Architect david.galloway@ibm.com IBM
