Yes they are created during the installation without doing nothing.
BUT they are first created with localhost instead of the host name of the server. Further more even if i create again the certificat with the good hostname i have to give to accept 2 different cert file to my client in order their browsers stop complainning.
This is such a pain to explain that the cert files are self signed to make them accept the first one , if you tr to make them accept a second one for the same server it 's impossible.
Besides it is common to use one certificat for one IP adress and with a cert file for each deamon running on the machine it is not the case.
So i would like to configure courier-imap-ssl, courier-pop-ssl, smtps and every service that are running on the server with only one certificate the one created for Ispconfig webserver that runs on port 81.
