In that case, Kairui needs to fix his sendmail config.

Maybe as you suggested, remove his own From: line  in this case. I
don't recall needing such a special git-send-mail config. Maybe
Kairui's smtp server is different.

BTW, I definitely know that Google's smtp server does not work well
with "b4 send --reflect".  Google SMTP is like: "Oh, I see you might
want to CC these people, because you include them in your inner
envelope CC list. let me do a CC for you on the outer envelope as
well". It defeats the purpose of "b4 send --reflect", which is a dry
run. I still recall the horror on my poor colleague's face when I
convinced him to try out "b4 send --reflect", which should be safe,
but the email actually sent out to the full list. I should file a bug
for that.
