Smtp with c# through gmail.

Lucas2

Hi guys,

hope you can help. I have installed Visual Web Developed and started learning ASP.NET with c#.

I am currently trying to build a website that sends email through gmail's smtp, here's the code:
_______________________________________________________________________
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Net.Mail;
using System.Net;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

System.Net.NetworkCredential cred = new System.Net.NetworkCredential("xxx@gmail.com", "xxx");

mail.To.Add("xxx@xxx.com");
mail.Subject = "subject";

mail.From = new System.Net.Mail.MailAddress("xxx@gmail.com");
mail.IsBodyHtml = true;
mail.Body = "message";

System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com");
smtp.UseDefaultCredentials = false;
smtp.EnableSsl = true;
smtp.Credentials = cred;
smtp.Port = 587;
smtp.Send(mail);
}
}

_______________________________________________________________________

And I am getting this error message:

Server Error in '/email' Application.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I am testing the app on the server that's integrated in Visual Web Developer, could that be the problem What else could it be

Please help.

Hi

the fact that you are testing in web dev should not have any impact.

the error you get looks like a timeout, so either your request never made it there, or it took too long.

do you have a firewall running if so, turn it off and try again.

Otherwise wrap your code in a try catch and see if there is any innerexception that gives you more detail..

Hope this helps, please close the thread if it does

indeed, its a good point picked up about the firewall - some firewalls block sending data from applications, be it a web app running from your box or a winform app - check the firewall, as suggested previously - the same applies for anti virus software too. In addition, be sure that the configuration settings are correctly configured for the gmail account
