We just deployed new SSL certificates for some of our services. Sending e-mails via our mail server no longer requires the import of our root CA certificate beforehand, but may require a restart of your e-mail client. Internal websites (like account management and password changing) or websites which are hosted by us and don't end in .ethz.ch got new certificates signed by our new root CA certificate. To avoid annoying and irritating warnings, we recommend you import our root CA certificate into your web browser.

The new root certificate will be installed in the web browsers on our managed workstations within the next days, too.
