I'm not aware of an existing way at the git level.  Here's the only
discussion I found about it on the git list:

  
https://lore.kernel.org/git/305577c2-709a-b632-4056-6582771176ac@redhat.com/T/#u

As a hacky/ugly way, for those that are okay tweaking the way their
names ends up on the mailing list, they can adjust `send-email --from=`
(or sendemail.from) slightly so that it doesn't match
user.name/user.email, and then send-email should take care of adding an
in-body header for user.name/user.email.

Another option is of course to feed the patches to a custom
post-processing script that adds the in-body "From:", where the details
would depend a bit on the person's patch workflow.

Or, moving that work a bit upstream, I think it'd be fairly
straightforward to wire up a prepare-commit-msg hook that would insert
an in-body "From:" (after checking some things, like whether the commit
is being amended).  I guess the main disadvantage of handling it at this
spot is the risk of commits with in-body "From:" headers unintentionally
being merged/pushed directly to the main line (given the person has
commit access).
