If you are having issues getting an SSL connection to Courier IMAP. Check your certificate files.
In /etc/courier/imapd-ssl:
TLS_CERTFILE=/etc/ssl/private/certificate.pem
Courier is expecting a PEM file for TLS_CERTFILE with your certificate and private key. Do not use just your certificate.
Also, if you require intermediate certificates to complete the trust chain, you can include them in this file.
MAKE SURE that you have proper permissions on this file to the security of your private key.
