Hello István and others,

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 :)
I am a self-employed Linux sysadmin in the Netherlands (Groningen), I do
some hosting on a small scale. I have my own closet and servers in a
datacenter 10 minutes from my home.
My configuration is: Cyrus IMAP, Postfix for SMTP, SOGo for webmail,
Debian as OS. All 100% open source.
In SOGo a user can configure ACLs for Cyrus, create Sieve filters and
configure auto-reply. Other features are caldav and carddav (also with
ACLs). I do not offer the Microsoft Activesync features of SOGo.
My e-mail service is not perfect, but I would like to become better ;-)
I guess also another provider what uses SOGo or Horde as webmail can do
what you want. I think Dovecot can also do ACLs and use Sieve.
With regards,
Paul van der Vlis
