[gopal2773]

Hi,
I am trying to send yahoo mail using socket program.
Using the commands like ehlo, starttls, auth login, data,.,quit.
but starttls is error. yahoo close itself. one more thing i use this same method for gmail is working.
The problem is we must enable the ssl authentication. Like System.net mail in .net package smtp.enablessl=true. how i enable ssl authentication in starttls in c++ program

You're using Windows, right? If then, I'll take a look...
