You shouldn't send email with a from address @nvidia.com from a server
other than NVIDIA's servers. If you do, plenty of people will drop the
email as SPAM, since NVIDIA publishes SPF[1] records (and perhaps other
email configuration) for nvidia.com. Since there are good reasons not to
use NVIDIA's email servers, that means: tell git the actual email
address you're sending from (for the email settings; you should set the
author/commit ID to your @nvidia.com address still).
