István,
One might think this obvious for a list hosted by Fastmail, but have you
considered Fastmail <https://www.fastmail.com/>? While Fastmail are
based in Melbourne, Australia, their servers are in various locations.
The other I would immediately think of is KolabNow
<https://kolabnow.com/>, based in the EU. Both are built upon Cyrus.
Fastmail is the lead developer of Cyrus, and has been for several
years. Kolab is also a major contributor to Cyrus.
The Fastmail option, (disclaimer: I do not use Fastmail, but have spent
time in their offices, working on Cyrus documentation, and think they're
all great folks) employs JMAP, capabilities which they built into Cyrus
in order to provide a more responsive user experience, and they have
great web and phone apps. I haven't worked with KolabNow, so cannot
speak to that experience.
Cheers,
-nic

Hi,
We run our own email server in-house for more than a decade now,
started with ClearOS 5.2, it's about 1.2TByte email.
Nowadays we will migrate to higher version of ClearOS with separate
cyrus 3.6.x imap, our tests seems fine with 3.6 (squatter works fine) etc.
But.
We also try to find a viable hosted email platform, which could
provide at least the following key properties:
* shared imap folders with ACL (obviously)
* sieve scripts
* imap heavy usage, all emails are on the server
* preferably EU vendor
Limits:
* no M$ o365
* no Google
Personally I just start to gather information about the potential
solutions, but I did not really convinced yet.
I mean, every provider have imap, spamfilter, user/white/blacklist
management, support desktop/web/mobile clients (imap, what is the
magic anyway) etc. standard features, price and other limits could
differ of course.
One potential candidate is Zimbra, which is not really my personal
favorite but seems it can share folders between users.
Thank you, I continue my own research too, I will keep you updated (or
just let me know to forgot it :)
