[ih] testing yours truly's iconia.com domain which has A Very Strict SPF/DMARC setting

[the keyboard of geoff goodfellow]

Thanks Brian! 😃

btw -- by yours truly reckoning iconia.com is even STRICTER than yahoo,
viz.:

(and if the IH list wants to see: if you forward this reply to the list it
would be interesting to see who will get/see this reply from yours truly
via the IH list "directly" -vs.- who will (only) get/see this reply via
your forwarding it to the list)

*SPF:*

strange:*~*% host -t txt iconia.com
