I host my email for now on a VPS with #Kopano. Unfortunately, the community edition was dropped and has been a messy ride, so not keen on upgrading to a subscription.

So looking for a new email arrangement. Need ~15 boxes, #ActiveSync, shared/public folders, and ideally managed without costing hundreds of bucks/mo.

Not a lot of options with ActiveSync (except #Microsoft, not going down that route). Thinking #SmarterMail? Any suggestions out there?
