I assume that you'd complain if it boiled down to a single bit?
0: "mail from this domain may transit manglers, adjust accordingly"
0: "I sign some mail"
Incorrect. They are *not* the same statement. "some" may mean
in reality (and often does) "none". Versus our domain signing every
piece of legitimate mail even if some of the signatures get broken
due to mailing lists.
If the signature is broken, the mail is not signed, so as far as the
recipient is concerned, they're the same. If you prefer the phrasing
"Some mail from me is signed", that works for me.
1: "the signature should always be intact"
1: "I sign all mail"
No. "I sign all mail" is merely a statement of fact. "should always
be intact"
is predictive. They are *not* the same.
As far as the recipient is concerned, they are. If you prefer
the phrasing "All mail from me is signed", go with that.
(The underlying problem of DKIM+SSP being unable to avoid
false-positive rejections in almost all cases if "I sign all mail" is
asserted is becoming clear here).
Cheers,
Steve
