Zoho's timeout as an external resource

Zoho's timeout as an external resource

Hello,
I am developing a website that will be sending a few mails using our email provider (zoho).
I believe there is a secuity stuff going on because it its always returning me timeouts.
I have tried disabling the two factor authentication/turning it on and adding "Application Specific Passwords" and still I am unable to send emails using smtp.zoho.com; port 465; my credentials; ssl is also enabled

Is it possible to do what i am trying to do? (tried a different provider for testing [gmail] and by disabling some extra security stuff I am able to send messages in my website).

Thanks for your help and time
