[issue45299] SMTP.send_message() does from mangling when it should not

R. David: `mangle_from_` is the only exception; I agree it seems likely it was done this way for backwards compatibility.

Grant: do you agree with the fix to logic? Also do you agree that mangle_from_ is the only setting that's not being applied to msg generation from message policy? Would you like to work on the PR? If not, I can create the PR.
