email setting configure error in telerik report server

Hi All,

I am using telerik report server to send email to recipient.But when i configure email setting under report server then it is giving me error:"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at".

My setting are:

smtp host: smtp.gmail.com

port: 587

use secure connection : check mark

account name: account name of telerik report server

pwd: ***********

sender email: my email address.gmail.com

Name: my name

then click on send test email.

Note i have checked the port 465 also.

Thanks,

Narender
