gmail smtp setting

in the installation process, the smtp server is must-have and no way to skip
I have a gmail account and try to use gmail as my smtp server
therefore, I input below information at the smtp setting page:
1.username: xx@gmail.com
2.password: yourpassword
3.smtp server: smtp.gmail.com
4.encrypt protocol: tls
5.port: 587
but it doesn’t work with poor message.
therefore, I debug the source of phpmailer and dump the error message from phpmailer.

i got an url than ask me to visit a google page
https://myaccount.google.com/u/1/security#connectedapps

there is a option “Allow Less Secure Apps” and remember to enable this option.
then, reload the step 4 again and it pass.

good luck!
