Hi, i've wrote a code to send email through the website. It works fine in Network Solutions hosting, but not in heliohost.org. My code is below. The form is located at http://www.crystalclear.heliohost.org/contactus.aspx. What could be causing it? Thanks so much.

using

 

 

System;

using

 

 

System.Collections.Generic;

using

 

 

System.Linq;

using

 

 

System.Web;

using

 

 

System.Web.UI;

using

 

 

System.Web.UI.WebControls;

using

 

 

System.Net.Mail;

namespace

 

 

WebApplication5

{

 

 

public partial class contactus : System.Web.UI.Page

{

 

 

protected void Page_Load(object sender, EventArgs e)

{

}

 

 

protected void Button1_Click(object sender, EventArgs e)

{

 

 

string bodystring = "Name: " + TextBox1.Text + " Email: " + TextBox2.Text + " Message: " + TextBox3.Text;

SendMail(TextBox2.Text, bodystring);

Response.Redirect(

 

"thankyou.aspx");

Response.Flush();

}

 

 

private void SendMail(string from, string body)

{

 

 

MailMessage message = new MailMessage("myemail@hotmail.com", "sendtoemail@hotmail.com", "Contact From Website", body);

 

 

SmtpClient mailClient = new SmtpClient("smtp.live.com", 25);

System.Net.

 

NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential("myemail@hotmail.com", "mypassword");

mailClient.DeliveryMethod = System.Net.Mail.

 

SmtpDeliveryMethod.Network;

　

mailClient.UseDefaultCredentials =

 

false;

mailClient.EnableSsl =

 

true;

mailClient.Credentials = SMTPUserInfo;

mailClient.Send(message);

message.Dispose();

}

}

}

The code is sound, and it works on NS you said, I have this strong suspicion that changing:

mailClient.EnableSsl = true;

to:

mailClient.EnableSsl = false;

will be the magic solution.

Hi Shynryuu, thanks so much for your reply. I've tried changing the enableSsl = false, but in that case i get an exception that something like "must issue starttls command first". Any other suggestions?

Thanks

I think you should switch the port number to 587, if that doesn't help I'm not really sure what does, that seems to be a common error with no clear-cut solution.

 

In the event it still gives an error, check your MX records and if those are good I'll just try to write up a slightly easier alternative.
