Dim ss As SmtpClient = New SmtpClient("smtp.gmail.com", 587) 
    'Dim ss As SmtpClient = New SmtpClient("smtp.gmail.com",465) 
    'Dim ss As SmtpClient = New SmtpClient("smtp.gmail.com", 25) 
    ss.Timeout = 10000 
    ss.DeliveryMethod = SmtpDeliveryMethod.Network 
    ss.UseDefaultCredentials = False 
    ss.EnableSsl = True 
    ss.UseDefaultCredentials = False 
    ss.Credentials = New NetworkCredential("name@gmail.com", "name@123") 


    Dim subject As String = "Approval request for Quotation with Order Number: " + Me.OrderNo 

    Dim body As String = "Dear Sir/Madam," + vbCrLf + " This is to bring to your notice the quotation for the Client " + Me.cmbCustomer.SelectedItem.Text + " and Order Number " + Me.OrderNo & _ 
     " which is awaiting your approval." + vbCrLf + "Click here to view and approve the Quotation: http:192.168.20.7/appname/Sales/ManageInvoices.aspx" + vbCrLf & _

    mm.Subject = subject 
    mm.Body = body 

    mm.BodyEncoding = UTF8Encoding.UTF8 
    'mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure 
    Try 
     ss.Send(mm) 
    Catch ex As SmtpException 
     Me.lblerr.Text = "SMTP Err:" & ex.ToString 
    End Try
