A little known fact is the Control Panel is eventually consistent for Cloud Containers. That means if a change is made directly on your server (like a container shuts down) or a job takes longer than we expect, that change will appear in the Control Panel soon(ish). We've now made this process much faster (push vs pull) – so the rare scenario where information might not have been quite up-to-date is now even rarer!
In some cases older email clients were getting tripped up by our mail servers SSL handshakes requirements. We've made some changes to make it handle things a bit more gracefully and hopefully prevent any issues.
