NAME

       mkdhparams - Create new DH parameters for the Courier Mail Server

SYNOPSIS

       /usr/sbin/mkdhparams

DESCRIPTION

       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.
