For the benefit of the list, I received a couple of off-list tip-offs to the link that Chrstopher suggested.
I was a bit cynical as I assumed the tool would only have effect on Google's external caches (i.e. 8.8.8.8).
The form was failing on Captcha on multiple browsers, which only helped to raise my level of unhappiness with Google.
After a bit of searching, I found the same form on another Google page and having plugged the details into the form, caches were indeed cleared both internally and externally at Google and gmails started arriving in the right place.
For the benefit of the list, was that https://dns.google/cache rather than the previously mentioned https://developers.google.com/speed/public-dns/cache ? --Niels.
