Configure git send mail for yahoo email

Hi All,

Could some one guide me how to configure .gitconfig 

I have tried following commands.

git config --global sendemail.smtpserver smtp.mail.yahoo.com
git config --global sendemail.smtpserverport 4100
git config --global sendemail.smtpencryption ssl
git config --global sendemail.smtpuser moon.linux at yahoo.com
git config --global sendemail.confirm auto


But I get following error:
Unable to initialize SMTP properly. Check config and use --smtp-debug.
