Gmail - Can't connect to zoho's smtp server

Hi,

Did anybody experienced that when I setup a "send mail as" account in gmail and I want to use the smtp server of zoho I got this:

SMTP Server:	Port:
Username:
Password:
	Secured connection using SSL (recommended) Secured connection using TLS
	Your other email provider is responding too slowly. Please try again later or contact the administrator of your other domain for further information.

Any resolution?

From mac "Mail" it just works fine.
