It's up to the maintainer accepting the patch. If I was picking up the
patch I would say it doesn't really matter if the mail-id is valid
anymore. Leave the original patch intact and just add your sign-off. If
you took the patch and significantly changed it it's good to put
"Based-on-a-patch-by:" and then take over authorship.
