[horde] Use of Horde with dovecot and caldav server (davical)

[David Brown]

Hi,

I don't know if this is the right place to ask about the suitability of 
Horde for a particular application, but if not I'd appreciate any pointers.


At the moment we have a Dovecot IMAP serving our mail system, along with 
exim4 for outgoing email.  I'm very happy with Dovecot, and have found 
it a fast and reliable imap server.  We have about 70 mail users, using 
either Thunderbird or Outlook on Windows, and a few Thunderbird users on 
Linux, along with a number of mobile telephones of various sorts.

We are looking for a number of new features:

- Web interface to mail.
- Centralised and shared calendars.
- Centralised and shared address books.
- Message filtering on the server side (for out-of-office replies, etc.)


I think Horde will give me that, or at least most of it, but I'm looking 
for confirmation here.

I'm hoping to keep Dovecot as the backend IMAP server, but I'm open to 
alternatives.  I would like to use caldav for the calenders, which will 
work fine with Thunderbird and (I think) most mobiles - and I believe 
there are third-party add-ons for Outlook.  The most likely caldav 
backend would be davical.


Am I looking in the right place here?  Or am I making life difficult for 
myself with this setup, and should rather be using different backend 
servers?  I am quite happy reading technical documents, doing 
installations, configuring things from web interfaces or command lines 
and config files as required, so I don't need a hand-holding 
installation process.  I just need a few tips to make sure I am heading 
in the right direction.

Many thanks,

David Brown
