This is my code but I get exception error why because my all code is to the point and correct.

protected void ButtonSend_Click(object sender, EventArgs e)

{

try

{

MailMessage mail = new MailMessage(TextBoxFrom.Text, TextBoxTo.Text, TextBoxSubject.Text, TextBoxBody.Text);

SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);

smtp.Credentials = new System.Net.NetworkCredential(TextBoxEmail.Text, TextBoxPassword.Text);

smtp.EnableSsl = true;

smtp.Send(mail);

Response.Write("Message sent successfully!");

}

catch (Exception ex)

{

Response.Write(ex.Message + " Some error's !");

}

Please teach me. Thanks a lot.

Hi,

First throw the exact exception.Instead of your catch code just use my code.
catch (Exception ex)
{
Throw ex;
}
Check my article for sending email using c# and possible error list. I think you are facing 5.5.1 authentication issue.check the following reference.

Hi Dear,
Use like this..

SendEmail("[email protected]","Test emai","body...")
protected string SendEmail(string toAddress, string subject, string body)
{
string result = “Message Sent Successfully..!!”;
string senderID = TextBoxEmail.Text// use sender’s email id here..
const string senderPassword = TextBoxPassword.Text; // sender password here…
try
{
SmtpClient smtp = new SmtpClient
{
Host = “smtp.gmail.com“, // smtp server address here…
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
Credentials = new System.Net.NetworkCredential(senderID, senderPassword),
Timeout = 30000,
};
MailMessage message = new MailMessage(senderID, toAddress, subject, body);
smtp.Send(message);
}
catch (Exception ex)
{
result = “Error sending email.!!!”;

}
