We use the secure encryption method TLS (Transport Layer Security) and PFS for e-mail transport. If the remote station supports this, the e-mail is transmitted in encrypted form.

As a further feature, users can encrypt e-mail using S/Mime and their own SSL certificates to prevent unauthorized access. In cooperation with Secorio, we offer our customers a 10% discount on S/MIME certificates. You can find more information on our S/MIME information page.

We host our server exclusively in German data centers.
