At the receiving end, "git am" will use the address on the "From:" header of the incoming e-mail and all should be well. Some mailing lists, however, mangle the From: address from what the original sender had; in such a situation, the user may want to add the in-body "From:" header even for their own patches. "git format-patch --[no-]force-in-body-from" was invented for such users.
