they chose this i= because that's the envelope from, but the i= is suppose

not a mechanical address, correct?
Historical bit: it is my impression that i= was invented by people who
were used to corporate mail systems where user identities are tightly
controlled and all the mail can be traced back to an individual user,
so the i= was that user's mail address.
At one stage i= was thought to represent different mail streams with different
reputation, however this did not get any traction...
