SslStream.Authenticate method

[nirmalsat]

Hi, I am trying to retrieve mails from a server like gmail. I have used TcpClient class to connect to the server.Connection is established successfully.During authentication using SslStream.AuthenticateAsClient() method to authenticate..I receive an exception saying..(HandShake Failed due to unexpected packet format).. Can anyone help me with this.. Thank you.

Probably the connection on the server side is not SSL. Or, you must first send some data (to identify you want to use SSL) to then call SslStream.Authenticate.
