If a matching certificate (with `.key` and `.csr` files) is found in `postfix/ssl`, it will be automatically configured in postfix. You just have to place `mail.my-domain.com.key` and `mail.my-domain.com.csr` for domain `mail.my-domain.com` in `postfix/ssl` folder. If a matching certificate (files listed above) is found in `postfix/ssl`, it will be automatically setup in postfix and courier-imap-ssl. You just have to place them in `postfix/ssl` folder.
