If desired, activate SSL for the various components of your server.

Basic configuration of all SSL functionality of the Apache web server. Add your own CA to the server before making these settings. Choose one of four possibilities for configuring SSL:

Everyone can initialize an encrypted connection to the server. Certificate-based authentication is not required.

optional

require
The client must supply a valid client certificate or the connection will be rejected.

optional_no_ca

Cyrus IMAPD SSL Basic Configuration

Activate SSL for IMAP and POP3. If you activate or deactivate SSL for POP3 or IMAP, the server must be restarted. This will close the connections for all clients.
