Gmail mailer authentication issue

Hi ,

I had try many different recommendations from the forum to solve the 500 error (mailer smtp authentication error), without success. I setup my gmail account for less secure apps, i disable two way authentication, i enable /disable ssl with no no luck!, Is any other issue that i must be aware that i cannot solve this ?

My current settings: SMTP server = smtp.gmail.com, port 465 SSL = enabled, username xxxxxx@gmail.com (i tried with the username without domain).
