[twsocket] email notification

Hello, To send a mail and ask a receive notification, witch one is common used, I find these 2 but they confuse me a little because I think they mean more or less the same: Disposition-Notification-To: [EMAIL PROTECTED] Return-Receipt-To: [EMAIL PROTECTED] -- Rgds, Wilfried
