Hi Falko or Till I installed ISPConfig using the Fedora 6 LAMP instructions. I've had ISPConfig running for a year and it shows because I am just now getting a certificate expired nag from Thunderbird. It says: mail.server.org is a site that uses a security certificate to encrypt data during transmission, but its certificate expired on 1.11.2008 3:22 PM. I regenerated the certs via Falko's instructions and rebooted the ISPConfig box but I get the same error in Thunderbird. When I view the certificate that expired it does not have the same data that I entered when I regenerated the keys. I've looked all over the system for this rogue certificate and am mystified where it could be located. I updated ISPConfig to the latest version this morning hoping that it would give me the cert generation options as if it was a new install but it updated and didn't give me that. Does anyone have a clue where these expired certificates could be and why I can't use the key generator in ISPConfig SSL area? Any assistance and a quick response would be very grateful.
