Email not working from Godaddy Server - asp.net

Question

First of all, I hope to be at the right place, I apologize in advance if this is not the case, please re-orient myself.
So here I have a worry, I have a website www.artipik.com with two forms, online quote and contact form.
My website is hosted by godaddy and servers were updated summers there for 15 days and my form are no longer work, which put me in a very problematic position. I'm a graphic designer not a coder, hence my difficulty changed the code.
I had the godaddy technical service and he gave it to me I think part of the solution. I found the place to change the code, but I can not seem to fit, I'm testing, I no further error messages but I do not receive any email I send.
My current ASP code is as follows:
<%
'-----version CDONTS-----
Set Mail = Server.CreateObject("CDONTS.NewMail")
Mail.BodyFormat = 1 '0:html/1:plain text
Mail.MailFormat = 1 '0:MIME/1:plain text
Mail.From = envoyeur
Mail.To = receveur
if copie<>vbnullstring then Mail.Bcc = copie
if sujet=vbnullstring then sujet="Formulaire de contact Artipik.com"
Mail.Subject = sujet
Mail.Body = message
Mail.Send
set Mail=Nothing
'response.cookies("email")=envoyeur
%>
and the new code that I have to adapt is the following (Using CDOSYS to Send Email from Your Windows Hosting Account):
// language -- C#
// import namespace
using System.Web.Mail;
private void SendEmail()
{
const string SERVER = "relay-hosting.secureserver.net";
MailMessage oMail = new System.Web.Mail.MailMessage();
oMail.From = "emailaddress#domainname";
oMail.To = "emailaddress#domainname";
oMail.Subject = "Test email subject";
oMail.BodyFormat = MailFormat.Html; // enumeration
oMail.Priority = MailPriority.High; // enumeration
oMail.Body = "Sent at: " + DateTime.Now;
SmtpMail.SmtpServer = SERVER;
SmtpMail.Send(oMail);
oMail = null; // free up resources
}
Thank you for your help.

Answer 1

System.Web.Mail.MailMessage is obsolete. You should use System.Net.Mail.MailMessage instead. It works almost exactly the same (warning! untested):
private void SendEmail()
{
using (var message = new MailMessage())
{
message.From = new MailAddress("emailaddress#domainname");
var toAddress = new MailAddress("emailaddress#domainname");
message.To.Add(toAddress);
message.Subject = "Test email subject";
message.Body = "Sent at: " + DateTime.Now;
message.Priority = MailPriority.High;
message.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Send(message);
}
}
Add this to your web.config:
<configuration>
<system.net>
<mailSettings>
<smtp from="emailaddress#domainname">
<network host="your-smtp-host-address" />
</smtp>
</mailSettings>
</system.net>
</configuration>

Recently I've had the same problem, could solve it throug the next way:
in web.config:
<system.net>
<mailSettings>
<smtp from="contacto#mydomain.com">
<network host="relay-hosting.secureserver.net" password="MyPass" port="25" enableSsl="false" defaultCredentials="false" userName="contacto#mydomain.com"/>
</smtp>
</mailSettings>
</system.net>
in codebehind:
MailMessage m = new MailMessage();
m.IsBodyHtml = true;
m.Body = "My Message";
m.To.Add("jhon.doe#yahoo.com");
m.Subject = "Go Daddy Emails Go Live!";
SmtpClient smtp = new SmtpClient();
smtp.Send(m);
