I have to following code:

Try
    Dim mail As New MailMessage()
    Dim SmtpServer As New SmtpClient("smtp.gmail.com")
    mail.From = New MailAddress(txtid.Text)
    mail.[To].Add(TextBox1.Text)
    mail.Subject = txtsub.Text
    mail.Body = txtmess.Text
    ' mail.Attachments.Add(New Attachment(OpenFileDialog1.FileName))
    SmtpServer.Port = 587
    SmtpServer.Credentials = New System.Net.NetworkCredential(txtid.Text, txtpass.Text)
    SmtpServer.EnableSsl = True

    SmtpServer.Send(mail)
    MsgBox("E-mail Has Been Send Successfully !")
Catch ex As Exception
    MsgBox(ex.Message)
End Try

on the step

SmtpServer.Send(mail)

I'm always getting an error : Failure sending mail

Any idea how to fix it?

Note that I'm using VB.NET

Try configuring your SMTP server on port 465 (with SSL) and port 587 (with TLS), works for me.
