Sending mail through Gmail using Zoho smtp: "535 Authentication Failed code(535)"

Sending mail through Gmail using Zoho smtp: "535 Authentication Failed code(535)"

Hi Zoho team! I am trying to send mail using Gmail through my Zoho account, but when I add my Zoho account I get the following error:


Authentication failed. Please check your username/password.
Server returned error: "535 Authentication Failed code(535) "

My username and password are correct and I am using SMTP server: smtp.zoho.com with a Port of 465 (SSL). I was wondering if I'm the only one who has this problem and if anyone can help me with this?

Thanks!
