We could pretend that the future is 8-bit clean, and hope the
problem will go away eventually.
+1 and it will. 8-bit is natural adaption expectation w/o DKIM.
Half the problem with the DKIM specs was that it was written with 6-7
years ago with semantics that are less important today.
Even then, the idea of making this a MUST would be, IMV, really
radical. An intermediary doing such downgrades would be behaving like
a Gateway:
ANY FORMAT --> GATEWAY --> RFC5322 --> DKIM SIGNER
It doesn't make sense for anyone to add DKIM in the gateway.
Murray,
Look at this way, the SHOULD is probably already ignore today. I
doubt a MUST will change that, and worst, force signers to write
simple cheap signing rules:
if mail contains 8-bit content, then skip signing.
