if you sure you have map correctly msgid with DLR url. you'll need to check how fast you can submit message to SMSC, you'll need to match with your submit to kannel. i'm sending around 150k messages per day, only miss around 100 DLR if smsc work correctly. if smsc got slow, kannel will build queue upto 10k messages. at that that DLR miss will be more 1k... thanks fajar
