Delivery reports work as event driven mechanism which informs you about the state of the message. This means that you have to specify the events (delivered to phone, not delivered to phone, queued on SMSC, rejected by the SMSC) for which you want to be informed. That's the role of the dlr-mask. With it we are specifying which events are we interested in. It's a bit mask, every bit is assigned to specific event. When you don't specify the dlr-mask the SMSC doesn't know if you want to receive delivery report and for which event you want to receive it. HTH, Jovan
