When sending a patch on someone else's behalf, you shouldn't send the e-mail with the sender (From header) set to someone else. You should use your normal address. The From line in the body of the message will make Git understand the author is someone else. So no new account setup required. I really recommend using git-send-email for patches. There are too many ways to make a mistake if you try sending emails manually. Here is a tutorial: https://git-send-email.io/ > Btw, if you have time, could you take a look in this series?
