using System.Net.Mail;

public partial class _Default : System.Web.UI.Page 
    #region  "Send email"
    protected void btnSendmail_Click(object sender, EventArgs e)
        // System.Web.Mail.SmtpMail.SmtpServer is obsolete in 2.0
        // System.Net.Mail.SmtpClient is the alternate class for this in 2.0
        SmtpClient smtpClient = new SmtpClient();
        MailMessage message = new MailMessage();

            MailAddress fromAddress = new MailAddress(txtEmail.Text, txtName.Text);

            //Default port will be 25

            message.Subject = "Feedback";

            // CC and BCC optional
            // MailAddressCollection class is used to send the email to various users

           // message.CC.Add("");

You need to set Relay IP-Address. (Relay restrictions).


1. Open IIS applet from the control panel
2. Go to0 Default SMTP Virtual Server
3. Select tab Access + Click on Relay.
4. Add IP of localhost

i want make software for window chat with text,picture,file,video,etc; i want use LAN connect server
.pls give me design for window and also code.

Additionally if you have Virus Scan Install,just disable 'Access Protection" and On- Delivery Email Scanner".
This wil help to send mail from your system.
