Magento transactional email setup

Magento transactional email setup

Hi team,

I am trying to send transaction emails in magento through by email id created in zoho. But I am getting an error while setting up the email setting. Can you please have a look and let me know what is the issue.
The issue is in the SMTP setting that I have been trying to setup. but zoho server is somehow not allowing it to be send.
Screenshot attached for your reference.

Thanks
Charles
