I had developed an ASP.NET website (C#). I had added the functionality to send mail. But the thing is that I can send mail from very few mail providers like Gmail, rediffmail,live,yahoo by using password. I want to send mail from every mail provider without using password. What should I do?? Please help me.

I am taking the inputs from user. But I don't want to take the password of his account. And if I declare the smtpserver=smtp.gmail.com then I can send mails form gmail ID only.. What about other IDs??

you can send to any other email by using Gamil userid and password but you can't send as someone else without using password of their account.

You CANNOT send mail from someone else's email account without knowing their credentials. That would be a major security vulnerability.

It doesn't matter how many times you ask, or how you phrase the question; what you are trying to do is IMPOSSIBLE.

You can apply dropdownlist through which user can choose the server and accordingly you have to give the server but in this only you have to limit the email servers

                    msg.From = Your Email Id;
                    msg.To = Reciever Id;
                    msg.Subject = "Subject";
                    msg.Body = "BODY OF MAIL
                    msg.Attachments.Add(new MailAttachment(List OF Attachment));
                    try
