I use gmail, and hence, I need to get a Google app password. After having the password, one has to setup ~/.gitconfig with content:
[sendemail] smtpEncryption = tls smtpServer = smtp.gmail.com smtpUser = <your id>@gmail.com smtpServerPort = 587 smtpPass = <your password>
Then you are able to use git send-email command:
git switch -c branch-patch git format-patch main git send-email 0001-***********.patch
prompt will ask some questions, an important one is which mailing list is your target? After command success, your patch are sent.
For certain git repository you're working on, can config local repository via git config --edit, and add below to omit email list in command line.
[sendemail] to = <target email list>
