Hello,
I am trying to get the contactform.acsx exercise going. I get the following error.

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. g14sm12076631rvb.52

The research I have done advises that the enablessl = true; command must be issued after declaring the mysmtpclient.
myMessage.To.Add(new MailAddress("[email protected]", "Receiver Name HEre"));

SmtpClient mySmtpClient = new SmtpClient();
mySmtpClient.EnableSsl = true;
try
{

mySmtpClient.Send(myMessage);

The thing is that i have done this in the contactform.ascx.cs file

and there is no change.

Help

Thanks

tomche

Hi tomche,

The error message also says "or the client was not authenticated". Maybe your ISP requires you to authenticate? Have you set a user name and password in the mail settings in the web.config file?
