Is this another closed source solution with a community edition?
I think of it as an open source solution with some paid-for features only really useful when running at commercial scale. A seemingly reasonable way to earn a living producing software.
Which begs the question, is there anyone comparing those solutions? Off the top of my head: zimbra, carbonio, openexchange, zarafa, citadel. I haven't even heard of most of those, and the one(s) I have don't seem to have any significant market share.
It's hard to say whether Stalwart has / will gain "momentum", but they say they're feature complete now, and it's a *highly* polished product. Need to know whether I can export messages in case I decide to move back to Postfix / Dovecot (there is an export command for the CLI tool, but it speaks of JMAP - would have to test if it can export to IMAP in MailDir format). Also, I have a script that uses inotify to trigger another script to rewrite new files (messages) in a specific folder, and resubmit them to IMAP with a meaningful subject. I don't know if that can be implemented in Stalwart. Gonna have to do some testing...
