Hi, I've certainly forgotten what I put in draft-ellermann-spf-eai-05
more than 6 years ago,
but apparently I thought that local part macros might not work as
expected (bad enough
to mention this also in the security considerations). At this time EAI
and SPF were still
experimental, and RFC 7208 was still Scott's draft. :-)

Unrelated Gmail observation, they tag SPF PASS + DKIM PASS + DMARC FAIL as spam.
