Dear all, In an attempt to tighten the security of our new Traso website, out proxy in front of the web server has been carefully modified: some state-of-the-art techniques have been implemented which brought our security rating <https://observatory.mozilla.org/analyze/www.traso.de> from Grade F to Grade B. Important: This affects all our systems which are reachable externally - including xadmin roundcube otrs wiki ... By now, everything looks fine. Please tell me if customers notify about problems accessing our systems.
