Previous responders said: o Maybe GMail doesn't allow sending emails without their web interface o Gmail doesn't allow to use SMTP in a classic way (normal auth with/without encryption).
I can confirm that GMail does allow sending emails through other means (not only “git send-email”, but any email client). But it is true that recently GMail removed the ability to use your the password of your Google account directly (remember “Less Secure Apps”?). Instead you'd have to use either OAuth2 or an app-specific password[1]. The relevant part of my gitconfig: [sendemail] smtpServer = smtp.gmail.com smtpServerPort = 587 smtpEncryption = tls smtpUser = 3nan.ajm...@gmail.com ; smtpPass = gmail app pass [1]: https://support.google.com/accounts/answer/185833?authuser=0 -- Enan 3nan.ajm...@gmail.com https://git.sr.ht/~enan/ https://www.github.com/3N4N
