I have been reading up on TLS and Dovecot and came across this URL: https://www.weakdh.org/sysadmin.html which recommended these settings for Dovecot. I would like to know if they are correct?

The current server installation & configuration is running since mid 2015, uptime of the server today is more than two months.
