Έγραψα τον εξής κώδικα για να στέλνω mail από μία φόρμα:
<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="iso-8859-7" %>
<%@ Import Namespace="System.Web.Mail" %>
...
<script runat="server">
void btnSubmit_Click(Object sender, EventArgs e) {
MailMessage objEmail = new MailMessage();
objEmail.To = "[email protected]"
objEmail.From = txtFrom.Text;
objEmail.Subject = "Μήνυμα από την φόρμα Επικοινωνίας";
objEmail.Body = txtName.Text + ", Τηλέφωνο: " + txtPhone.Text +"\n ", email: " + txtFrom.Text + " : " + txtComments.Text;
objEmail.Priority = MailPriority.High;
objEmail.BodyFormat = MailFormat.Html;
SmtpMail.SmtpServer = "localhost";
try{
SmtpMail.Send(objEmail);
txtMessage.Text="Ευχαριστούμε για την παρατήρησή σας";
txtName.Text="";
txtFrom.Text="";
txtPhone.Text="";
txtComments.Text="";
}
catch (Exception exc){
txtMessage.Text="Αποτυχία αποστολής: " + exc.ToString();
}
}
</script>, ο οποίος λειτουργεί κανονικά σε μένα που βάζω το smtp του παροχέα μου για να στέλνει τα mail αλλά στο hosting που έχω βάλει localhost μου βγάζει το εξής η εφαρμογή:
