What if the DLR are received on the next day of firing the campaign?

 In such case, the iTextHub will match the message id received in the DLR packet and will replace the status of that particular message to the DLR message status in the List view.

Example: If a Message is submitted on 08-08-2019 20:09:56 and a DLR (DELIVERED) is received at 09-08-2019 16:40:35, iText will match the message ID of both packets and will replace SUBMITTED to DELIVERED and will display DELIVERED on 08-08-2019 20:09:56 in the List View.
