Forward Secrecy in the Postfix SMTP Client

[Mike]

On this page:
http://www.postfix.org/FORWARD_SECRECY_README.html#client_fs



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.
