@Gina why'd you go with Kopano instead of something like Mailcow (https://mailcow.email/)? Just curious, I'm investigating my own organizational email solution currently.
@jonah also, are you looking at on-premise or a cloud service for your email?
@Gina on-prem for sure, third parties having access to our data is a concern.
@jonah we have this concern too, which is why we chose on-premise, but at the same time it's getting harder to defend not using Protonmail or Tutanota.
@jonah Mailcow is nice, but I think it's meant more for private use than for business use.
