I love ispconfig so far and most things I have had problems with are problems I created. For instance. In my apache error.log I get this: [ssl:warn] [pid 9721] AH01906: mail.linuxnuts.com:6969:0 server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) [Thu Nov 10 05:21:14.566338 2016] [ssl:warn] [pid 9721] AH01909: mail.linuxnuts.com:6969:0 server certificate does NOT include an ID which matches the server name [Thu Nov 10 05:21:14.566428 2016] [ssl:error] [pid 9721] AH02217: ssl_stapling_init_cert: can't retrieve issuer certificate!

Is there a snippet of code in the install.php I can run to create and recopy the cert to the email configuration?
