New certificates for Unimail and Webmail TU Dortmund
New certificates were issued for the two servers Unimail and Webmail.
Since the DFN-PKI has outsourced its certificate service, they are no longer signed by the DFN-CA, but by the "GEANT Vereniging" from the Netherlands.
This is correct and will apply to all new certificates at TU Dortmund by the end of the year at the latest.
