Thanks very much for your prompt answer and fixing.
I already updated from 5.0.36 to 5.0.38 and all works fine so far.
I will soon update my HOWTO in Internet.
I also saw the graphic enhancements of small icons for features in the interface. Cool.
I really appreciate your good work and although I haven't tested your product all the way through yet,
I already have a very good feeling about it,
especially in the area of quality, performance and support of the product.
I'm working as consultant and Sysadmin for commercial clients
and especially since the NSA having its nose in almost all of our networks,
there is a demand for secure email services which I'm trying to set-up fro myself and for clients.
The combination of high functionality and flexibility for admins to still introduce their own internal extra functions
is the best I've seen so far. Very often, in order to raise the functionality
and ease of use software, companies are making the core of the system 'intransparent'
and very difficult to manipulate without breaking the system.
A good example of that undesirable attitude is Zimbra.
One of my client is using it but I'm trying to convince him to change
to Group Office where much more flexibility is available.
Group Office is in my opinion a great work and concept.
I will test the system much more for my own use and I'mm looking forward to it.
IT Matrix Berlin.
PS. Although I probably should not say that but, the fact that your company is in Holland and not In USA is a big plus for me.
