Installing an SSL in Courier IMAP and POP3

After your certificate request is approved, you can download your SSL and intermediate certificate from within the SSL application. For more information, see Downloading Your SSL Certificate. Both of these files must be installed on your Web server.

To Install Your SSL and Intermediate Certificate

  • 1. Gather your certificate files. Log in to your SSL Manager and download your primary and intermediate certificates. You also need your private key (your_domain.key), which was generated by your server along with your CSR.
  • 2. Create a combined .pem certificate file. Using a text editor such as Notepad, paste in the contents of the primary certificate and your private key, including the BEGIN and END tags. For example:

-----BEGIN CERTIFICATE-----
(Your primary certificate: your_domain.crt)
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
(Your private key: your_domain.key)
-----END RSA PRIVATE KEY-----

  • Save the file as sfcertpack.pem
  • 3. Save the Starfield intermediate certificate. Copy the Starfield intermediate certificate into a text editor and save the file as sfca.txt
  • 4. Secure Courier IMAP. Locate and open imapd-ssl file (usually found in /usr/lib/courier-imap/etc/). Add the following directives and file locations:

TLS_CERTFILE=/some/path/sfcertpack.pem

TLS_CERTFILE=/some/path/sfca.txt

  • Verify that the line below is allowing SSL3:

TLS_PROTOCOL=SSL3

  • 5. Secure POP3. Locate and open pop3d-ssl file (typically found in /usr/lib/courier-imap/etc/). Add the following directives and file locations:

TLS_CERTFILE=/some/path/sfcertpack.pem

TLS_CERTFILE=/some/path/sfca.txt

  • 6. Verify your file permissions. Ensure sfcertpack.pem is readable by root only.
  • 7. Restart your Courier IMAP server.
