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.

No. "I sign all mail" is merely a statement of fact. "should always be 
intact"
is predictive. They are *not* the same.
