I guess I’ll put this in the newbie category since I’ve taken over from an admin who talked a good game but didn’t deliver. I’ve run Virtualmin since Ubuntu 12 and it’s been pretty good. We recently went to 2 factor on Virtualmin and then had a loss of the google side of the account. I roughed through that and got the system back up but we’ve lost email on 5 domains and I’m not making progress. I even went so far as to provision a fresh server, but that install had errors and isn’t much better off.
The broken mail system has serious certificate problems. I can’t get postfix/dovcot to change or update the certificate, so we can’t access mail.

Any tips?
