Wordpress Activation email not being sent, using zoho mail

Wordpress Activation email not being sent, using zoho mail

Users are not receiving the WP Activation emails. My 'from' email is a Zoho mail account. I've got 'Send all WP emails via SMTP' selected. For SMTP Options, the host is smtp.zoho.com, port 465, using SSL, and Yes: Use SMTP authn.

I'm not able to send a Test Email either. 

I'm running on WP 4.4.10 and the website is lookfitfeel.com, hosted on GoDaddy.

TIA,
Jim
