Bill,
Thanks for the in depth info regarding both questions.
And I can confirm that CGP did a lot of work on the CalDAV ( and it took
us quite some escalation and perseverance to have an difficult and most
annoying issue resolved ) but sofa is the result OK.
Thanks again
Marc

Dear MM list-users,
We are looking for advice for a good, very functional, well

that runs on OSX
Dovecot is absolutely the IMAP server of choice for just about any
Unix-like OS where you don't have specialized needs for things it just
doesn't do. You can install from distribution source yourself or use
either MacPorts or Homebrew if you prefer or already use one of them
for software management. OR: see below
Eventually one that also supports calendar functionality ( CalDAV, .
. .)
Yeah, that's a different thing...
MacOS Server (these days a VERY affordable compound app that installs
on standard MacOS X, not a pricey alternate version of the OS)
includes slightly customized versions of Dovecot and Postfix with a
reasonably good working config integrating them AND a CalDAV server
that is essentially the reference implementation of the CalDAV
spec(s). Unfortunately the CalDAV specs include some widely-expected
extensions which seem to confuse implementors on both client and
server sides to the point where interop really sucks. Mail/calendar
integration is the worst of it, to the point where both Google and
Apple don't even seriously try to follow the RFC defining how a CalDAV
server should do invites and change notifications on their public
services. I'm not actually sure how well the integration in MacOS X
Server is, but it's there, it's supported for a low price, and if you
prefer a GUI to manage a mail server, that's what you're getting. If
you prefer managing a mail server in a terminal, DO NOT use
Server.app: it will punish you for fiddling.
If "we" consists of a small number of people (i.e. a family or tiny
business) you might also want to consider CommuniGatePro, an
integrated "Universal Communication Server" meant to compare to MS
Exchange. It is free for a small number of users and functional for
more without a license except that it tags all outgoing messages with
a note that it's a trial version when you go over the free limit (I
don't recall if it is 5 or 10 users currently...) Paid pricing for CGP
might be deemed "not too expensive" in the right frame of reference.
Its CalDAV integration has evolved over the years from quasi-fraud to
pretty solid. CGP is a truly integrated server (one closed-source
binary daemon for
SMTP/POP/IMAP/LDAP/SIP/XMPP/CalDAV/CardDAV/WebDAV/etc.) unlike MacOS X
Server (a couple dozen daemons dressed up in a single duct-taped
trenchcoat...) or a standalone Dovecot (which is great at IMAP and POP
but doesn't send or receive mail on its own). Since CGP has a web
admin GUI you may prefer it over Dovecot's deeply versatile and
possibly confusing maze of config files or the oversimplified and
mandatory GUI layer that Server wraps around Dovecot's complexity.
However, mif you really ONLY want IMAP and CalDAV, you can get Dovecot
in prepackaged or source form and the latest from calendarserver.org
and wire them together yourself, hooking into the Mac's built-in
trivial Postfix installation as/if needed. Getting to that state with
Server.app or CGP would be a lot of pointing and clicking to turn
stuff off.
(full disclosure: I make my living in part by managing multiple mail
systems, which include Postfix+Dovecot, MacOS X Server, and CGP
environments. They all suck, each in their own special unique ways...)
