There is: Once the parameters are in place, update main.cf as follows: /etc/postfix/main.cf: smtpd_tls_dh1024_param_file = ${config_directory}/dh2048.pem smtpd_tls_dh512_param_file = ${config_directory}/dh512.pem I notice the line starting with 'smtpd_tls_dh1024_param_file' points to a 2048 file. Is that correct, or might it be a typo? thanks.
