Courier IMAP

Installing your SSL Certificate / Web Server Certificate / Secure Server Certificate from RapidSSL.com

Firstly when your issuance email arrives you will find your server certificate within the body of the email.

1. Copy your server certificate from the body of the email into a new file. Copy the contents of your private key file (yourdomain.key) into the same file. yourdomain.key - which will have been generated by your server when the original CSR was created. The final file should look like:

-----BEGIN CERTIFICATE-----
..................
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
..................
-----END RSA PRIVATE KEY-----

Ensure that there are NO blank lines between the key and certificate.

2. Save the certificate plus private key file as yourdomain_cert_key, and save to a suitable location.

• Locate and open imapd-ssl file (typically found in /usr/lib/courier-imap/etc/). Add the following directives and file locations:
  
  TLS_CERTFILE=/some/path/openguild_cert_and_key
  

4. To secure your POP3:

• Locate and open pop3d-ssl file (typically found in /usr/lib/courier-imap/etc/). Add the following directives and file locations:
