dgrig, you've correctly identified the state of things. The summary at the top of https://github.com/NixOS/infra/issues/485 is accurate. We need to set up some alerts for the mailserver. I just haven't taken the time to familiarize myself with prometheus and the blackbox alerting we have set up on pluto. I don't think there's a lot of work remaining there.

Here's an idea that feels low risk: we could set up this new mailserver to send emails alongside our existing improvmx account. That would let us start to test out this arrangment without breaking any existing send accounts.

For receiving, we have to either:

• complete the rollout
• OR, use improvmx to set up additional mailing lists

Do you have a sense of the timeline you're working on here?

team members receiving emails to a team's nixos.org address (should be somewhat easy to keep up to date who's in the recipient list, ideally eventually auto-synced with whatever mechanism is available for managing teams)

This is news to me. Is this github teams? Or something TBD that'll be used for sign-on to our new grist service?

I don't have an exact timeline, but I think it would be around sometime next week.

If improvmx can send emails then it's good enough for this usecase now I think and there's no need to worry about potential issues with the new setup.
