Courier Mail Server                                01/22/2022                                      MKDHPARAMS(8)

       This script is intended to be executed from a cron job, monthly. If the file /etc/courier/dhparams.pem is
       older than 25 days, the script creates a new file. This file contains pregenerated DH parameters for the
       Courier Mail Server.

       The DH_BITS environment variable, if set controls the length of the generated DH parameters. It gets
       passed, verbatim, to either the dhparam OpenSSL command, or the --sec-param option to GnuTLS's certtool.
       The default value is 768 for OpenSSL, and “high” for GnuTLS.
