How to set SSL True for ASP.Net PasswordRecovery control when using GMAIL SMTP Server

HI,

    My PasswordRecovery Control is not working. It is giving me SMTP problem. I set my proper gmail address with port number, valid user name and password. But not working? Do I require to set more settings?

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. pg3sm5232120pbc.2

Web.config :

<system.net> <mailSettings> <smtp from="myemailid@Gmail.com"> <network host="smtp.gmail.com" password="mypassword" port="587" userName="myemailid@Gmail.com" /> </smtp> </mailSettings> </system.net>
