Is it perhaps better to just say "editheader operations MUST NOT modify
those four fields"?
This is definetely better. I've not seen those header fields ever being
modified by intermediate MTAs (forwarders, mail lists, etc) nor is there
any reason why they should by MDAs or their agents. The only thing is that
Content-Transfer-Encoding may in theory be subject to changes if MDA wants
to decode BASE64 into something more readable for MUAs (in theory it should
not try though).
That's not relevant to the editheader extension.
The point is that if MDAs do it, so could SIEVE system to make it easier
for other rules, but it really should not care about it and let other
rules work with data that is in BASE64 same as if was clear text.
And I'm not entirely sure if that is actually mentioned or not.
