For now, running (with a real resolver address instead of 192.0.2.1)

  dig @192.0.2.1 $RANDOM. +dnssec

and checking if a certain percentage of the responses include DNSSEC
data.  This means that your resolver can get data from DURZ-enabled
servers, so you should be fine when the root is signed.

If your resolvers are not security-aware, use 

  dig @192.0.2.1 . NSEC
  dig @192.0.2.1 . RRSIG
  dig @192.0.2.1 . DNSKEY

but you can run this variant of the test only once per day.

If you never, ever get any DNSSEC data for these queries, you will
very likely have a problem once all root servers have switched to
serving DURZ (and later DNSSEC) data.

Why do you think so? Would you even notice if your webmail provider
switches to HTTPS by default (or back to HTTP)?
