Me again…

After some investigation in the problem, I had to find out that the update module simply ignores the system proxy settings completely:

It tries to communicate with the update-servers (at least with two IP-addresses) directly per http (port 80).

So the workaround would be to allow my Mac to allow a range of servers (is a list for the update-servers available?).

Probably the best solution would be the update-module takes care about the system settings…
