New security certificates
Created at 17.January 2017, 10:00 | Category: Info
Dear Posteo users,
In the coming days we will be updating our security certificates. Security certificates are only valid for a specified time period and need to be renewed from time to time. We will therefore be changing them by 22.01.2017. We continue to use certificates from Geotrust and the Bundesdruckerei (D-Trust).
In most cases you will not notice anything when the certificates are changed over. All programs such as Thunderbird or Outlook will find the new certificate automatically. You do not need to do anything. If your program displays a certificate error during the changeover process, please simply restart the program, which should overcome the error.
If you check the trustworthiness of certificates manually, you can find the fingerprints for the new certificates that we will shortly begin using, below. You can also find the fingerprints in our legal notice.
