Hard codes groups for now; they need to be migrated to a userdb data source.

Had to hardcode the userdb IP.... dns lookups are failing with:

This will happen for the next year ish, because most popular mail hosts have a ranking system based on the age of the IP to prevent people from just picking up a new host and using mail on it.

I don't know why it happens for DigitalOcean IPs, as if I recall correctly, mail is blocked by default, so we had to open up an issue a very long time ago to get it activated for our account. I guess Google doesn't care.

our SPF records say only accept mail from our MX; need to update it to allow from any k8s node running mail....
