fyi guys, if you want to send email using hotmail you have to use the following code:
Note the two key lines: port number is set to 587 and enablessl is set because hotmail uses SecureSocketsLayer on its connections. The email that is sent says :
From: [the server email account adress] on behalf of [name of person account is registered to] ([the email address you put as from i.e. a@bb.net])
This means you cannot create fake emails through Hotmail without the receiver knowing
Hope this helps, Ed
SmtpClient client = new SmtpClient("smtp.live.com");
MailMessage message = new MailMessage("a@bb.net", "lukyperson@somewhere.com");
message.Body = "Some text";
message.Subject = "A subject";
client.Credentials = new System.Net.NetworkCredential(Username, Password);
/*---->*/ client.Port = 587;
/*---->*/ client.EnableSsl = true;
client.Send(message);

catch (Exception ex)
{
//show error
MessageBox.Show("can't send message: "+ex.Message);
}
I receive this error from the exception, when I click on send button.
I'm a beginner with c#.

I think that error message is pretty self-explanatory. The From parameter(the first parameter) can't be blank.

I somehow set my email Username, Password, Host and Port in web.config file.
When sending email, it actually send from the email I set.
Is it possible to not displaying my email but display "noreply@mydomain.com" to receiver?
