I just want to implement one sample mail sending application. I have done lot of research for this. From all the corners I am getting same kind of solution. But that is not working for me.I am unable to find my mistake. I am using below code
protected void SendEmail(object sender, EventArgs e)
{
string to = txtTo.Text;
string from = txtEmail.Text;
string subject = txtSubject.Text;
string body = txtBody.Text;
using (MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text))
{
mm.Subject = txtSubject.Text;
mm.Body = txtBody.Text;
if (fuAttachment.HasFile)
{
string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential NetworkCred = new NetworkCredential(txtEmail.Text, txtPassword.Text);
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Email sent.');", true);
}
}
And getting the exception like below
please suggest me how can I solve this issue.
Thanks in advance.
Assuming that you are using a correct Gmail credentials for the account with which you are sending emails. You need to turn on "less secure apps" setting using the below link: https://www.google.com/settings/u/1/security/lesssecureapps
