Well, I tried that Eric. The expected solution would be enabling this git setting: git config [--global] format.from true https://git-scm.com/docs/git-config#Documentation/git-config.txt-formatfrom But as you can already read from the manual, the overall behaviour of git regarding a separate "From:" line in the email body was intended solely for the use case sender != author. So in practice (at least in my git version) git always makes a raw string comparison between sender (name and email) string and author string and only adds the separate From: line to the body if they differ. Hence also "git format-patch --from=" only works here if you use a different author string (name and email) there, otherwise on a perfect string match it is simply ignored and you end up with only one "From:" in the email header. So eventually I added one extra character in my name for now and removed it manually in the dumped emails subsequently (see today's "[PATCH v7 0/3] 9p: Fix file ID collisions"). Besides that direct string comparison restriction; git also seems to have a bug here. Because even if you have sender != author, then git falsely uses author as sender of the cover letter, whereas the emails of the individual patches are encoded correctly.
