# Make sure that `git send-email` is configured properly in your Git config.

|

# Here is an example config for Gmail:
|
||||
#
|
||||
# [sendemail]
|
||||
# smtpencryption = tls
|
||||
# smtpserver = smtp.gmail.com
|

# smtpuser = your-user@gmail.com
|
||||
# smtpserverport = 587
|
||||
# from = Firstname Lastname <your-user@gmail.com>
|
||||
#
|
||||
# In addition you need to enable "less securs apps" in Gmail:
