Re: SMSC Rejected DLR shouldn't be saved in the DLR storage

I user dlr-mask = 31 ( kannel stable release 64-bits 1.4.3)

Hello people, thanks so much for your great answers, but my problem is not
with understanding the DLR mechanism in Kannel, I already know that, but my
question is: Why kannel stores DLRs in the DLR table for the SMS-Rejected
MTs (status = 16)? When the SMSC rejects an MT then it will forget about it
and it won't send any DLR for for that MT in the future, so Kannel shouldn't
insert a record into the DLR table? right?


Thanks
