Mac OS X Server v10.6: Enabling a SSL chained certificate for mail services

When enabling SSL for POP and IMAP on a Mac OS X v10.6 Mail Server, SSL encryption may not work if the server uses a chained certificate. The steps below explain how to enable the ssl_ca_file key for SSL.

Install the Mac OS X Server v10.6.2 Update or later, then enable SSL as described in Mail Service Admin Guide.

In Mac OS X Server v10.6 and v10.6.1, you can enable this feature by modifying the dovecot.conf file after enabling SSL in Server Admin Mail.

  1. Open the /etc/dovecot/dovecot.conf file in a text editor.
  2. Look for the ssl_ca_file key.  It will look something like this:
    #ssl_ca_file = /etc/certificates/
  3. Remove the # character, so that the key begins like this:

      ssl_ca_file = ...
  4. Save the file.
  5. Restart the mail service.
