For n != 4409 (formerly 2476), its "MAY add Sender" isn't "just
modify From".  They can reject all your submissions until you
use jcallas@, they can even modify the From if that's in their
AUP and you agreed.  They shouldn't silently introduce such
modifications without informing you.  Maybe you have important
reasons when you don't want to use jcallas at .
