mkdhparams8
Create new dh parameters for the courier mail server
Usage
/usr/sbin/mkdhparams
Overview
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.
