It may ne possible that a very old device running something like iOS 4 or maybe
5 does not support TLS1.2, but it is very unlikely anyone is using a device
that old, and they are not able to check mail with most providers.
(I know for certain that iOS 8 supported TLSv1.2, but I am unsure what version
of iOS added support for it, I would guess it was around iOS 6. TLSv1.3 was
added in iOS 11.)

There used to be such simple directions, back in the days before they

Backward and Forward, Past and Future... But normal directions
don't work in the multiverse, which has far too many dimensions
for anyone to find their way. So new ones have to be invented so
that the way can be found. Like: East of the Sun, West of the
Moon Or: Behind the North Wind. Or: At the Back of Beyond. Or:
There and Back Again. Or: Beyond the Fields We Know. --Lords and
