As mentioned in this thread:
...I am looking among other things, about something to replace my Exchange server.
I see KerioConnect is a possible alternative supporting mail/contacts/calendar. Correct?
I also see in the vendor's site, that KerioConnect is nowadays commercial.
So... will this plugin work? I see it is based on a build a few years ago and never updated.
Also, does this server support pop-connector functionality? (i.e. download email from other server)
Is this plugin maintained at all?
Any alternative for mail/contacts/calendar?
