Setting STMP for zoho not working.

Setting STMP for zoho not working.

I trying to send mail via zoho smtp.

I register my domain and create account like this --> sale@siamwarzone.com

I using ASP.NET. Here is setting in web.config.

  1. <system.net>
  2.     <mailSettings>
  3.         <smtp deliveryMethod="Network" from="sale@siamwarzone.com">
  4.             <network host="smtp.zoho.com" userName="sale@siamwarzone.com" password="{mypassword}" port="465" defaultCredentials="false" enableSsl="true" />
  5.         </smtp>
  6.     </mailSettings>
  7.   </system.net>

When i send, it wait for long time, then throw exception --> "Unable to read data from the transport connection: net_io_connectionclosed".

I use the same code, but gmail account. It's work well.

How can i solve this problem, please help.
