            System.Net.Security.SslStream sslstream = new SslStream(tcpclient.GetStream()); // This is Secure Stream // opened the connection between client and POP Server

                }
                str += strTemp;
            }
            Response.Write(str);
            Response.Write("" + "Congratulation.. ....!!! You read your first gmail email ");
        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }

can anyone please tell me how can i get the actual mails from the inbox.

Answer 1

1. You should read server responses as soon as you issue a command.
2. You have not logged in to Gmail successfully - you should use POP3 commands like USER, PASS
3. Your code fails if email contains "-ERR" text
4. str += strTemp; is going to kill your app when you revive email with a large attachment

I'd recommend not reinventing the wheel - there are libraries for POP3 access.

Answer 2

Have you had a look at Mail.net, I have not had need to use it myself but I here good things about it.
