Hi Jaap,
   Using Apache2, this is what I've done that works.  I have a web 
server on a different computer that handles all my traffic for my 
domain.  This computer has the SSL certificate assigned to it, then uses 
a "home built" certificate internally.  I'm using this with Horde 5.2.22.

   The one thing that I don't have working yet is syncing my phones to 
Horde for calendar and addresses.

   I hope it helps.

and port that
         # the server uses to identify itself. This is used when creating

         # specifies what hostname must appear in the request's Host:

         # value is not decisive as it is used as a last resort host
