Just before i go out and starting making them i just want to be sure. 1 SSL = 1 IP, understandable! Currently i don't have SSL 'activated' for any site since i have only 1 ip. I do have 1 cert created, the one from installation. Can i make new cert for mail.domain.tpl and www.domain.tpl? Can i make cert for each domain name without using SSL... Where are certs located, path? The thing that bothers me is that i get error mismatch when checking mail. So if i create cert with mail.domain.tpl, that should go away. Again, i'm not asking if i can have more then 1 SSL on 1 IP. SSL is off Hope you know what i mean.. If possible, i can just repeat steps from installation tutorial. Just checking...
You are mixing up things, especially certs for Postfix and Apache! You mean the cert for the ISPConfig web interface? It has no effect on the number of Apache certs you can install because ISPConfig runs on port 81. It is 1 cert per IP AND port. You can make a new Postfix cert by redoing the steps from the tutorial. Yes, use ISPConfig for it. Postfix certs: /etc/postfix/ssl. Apache certs: e.g. /var/www/web1/ssl
