My e-mail-client returns an error message each time I try to add the menten certificate to the certificate list – where am I wrong?
Dont worry – youre not wrong at all but have simply forgotten to keep in mind that: The menten certificate is based upon the root certificate of Deutsche Telekom, which in turn is built upon the root certificate of GlobalSign and the rootcertificate for partners of GlobalSign. You can achieve the highest degree of trustability and the best protection for your e-mail communication by not only using a certificate (like the menten certificate), but by applying the root certificates on which the certificate is based upon in addition. Thats why you should not hesitate to download the root certificates of Deutsche Telecom and Cybertrust as well. If you are only applying the menten certificate and resign to use the root certificate of Deutsche Telecom, the rootcertificate of GlobalSign and the rootcertificate for partners of GlobalSign in addition, your e-mail-client will draw to your attention that the menten certificate cannot be definitely assigned. Please take our advise and add both root
