SSL Courier IMAP certificate on Debian

Easy way to create a new certificate instead of the autogenerated one which comes with “apt-get install courier-imap-ssl”:

• check your /etc/courier/imapd.cnf
• move the file /etc/courier/imapd.pem to another name or location
• dpkg-reconfigure courier-imap-ssl
• restart imapd and check if everything was ok
