I checked my domain, and it turns out somehow my MX record got blown
away. Also a while back I canceled No-Ip Plus managed DNS, thinking it
was only used for dynamic DNS, but in the process I threw away my SPF
record which I've now recreated after re-enabling Plus. Also lost my
DKIM record which I've recreated. We'll see if that resolves anything.
Thanks for your pointers.
