And my Glbal.asax file looks like this

Code:
<%@ Application Language="C#" %>
<%@ Import Namespace="System.Net.Mail" %>
<script runat="server">
void Application_Start(object sender, EventArgs e) 
{
// Code that runs on application startup
}
 
void Application_End(object sender, EventArgs e) 
{
// Code that runs on application shutdown
}
 
void Application_Error(object sender, EventArgs e) 
{ 
if (HttpContext.Current.Server.GetLastError() != null)
{
Exception myException = HttpContext.Current.Server.GetLastError().GetBaseException();
string mailSubject = "Error in page " + Request.Url.ToString();
string message = string.Empty;
message += "<strong>Message</strong><br />" + myException.StackTrace + "<br />";
message += "<strong>Query String</strong><br />" + Request.QueryString.ToString() +
"<br />";
SmtpClient mySmtpClient = new SmtpClient();
MailMessage myMessage = new MailMessage("stemcell74@gmail.com",
"stemcell74@gmail.com", mailSubject, message);
myMessage.IsBodyHtml = true;
mySmtpClient.Send(myMessage);
}
}
void Session_Start(object sender, EventArgs e) 
{
// Code that runs when a new session is started
}
void Session_End(object sender, EventArgs e) 
{
// Code that runs when a session ends. 
// Note: The Session_End event is raised only when the sessionstate mode
// is set to InProc in the Web.config file. If session mode is set to StateServer 
// or SQLServer, the event is not raised.
}
 
</script>
All the other smtp examples from the book now work.

The internet connection is fine so I am at a loss as to what could be the problem.

Any help would be most apprecaited

Cheers

Tomche

Hi Tomche,

Isn't this the exact same problem as with the other mail examples? You're not setting the EnableSsl property to true on the SmtpClient while your Gmail mail server requires that property to be set....

Thanks Imar you are a legend.

I changed the code to the following

message += "<strong>Query String</strong><br />" + Request.QueryString.ToString() + "<br />";

SmtpClient mySmtpClient = newSmtpClient();
MailMessage myMessage = newMailMessage("stemcell74@gmail.com",
"stemcell74@gmail.com", mailSubject, message);
mySmtpClient.Port = 587;
mySmtpClient.Credentials =
new System.Net.NetworkCredential("stemcell74@gmail.com", "mypassword");
mySmtpClient.EnableSsl =
true;
myMessage.IsBodyHtml =
true;
mySmtpClient.Send(myMessage);
}
}
void Session_Start(object sender, EventArgs e)


Cheeers
