The queued DLRs, are as you initially suggest, they are waiting on the final
response from the SMSC, i.e. until they get either delivered or an
undeliverable (or a rejected submission) they will hang around waiting for
that (assuming the mask you set is looking for them). I think queued is
perhaps the wrong word to use really. Pending might well be better.
As far as I am aware, if a DLR fails to be delivered it is not queued for a
redelivery attempt.
okay, so the reason so many are queued is possibly due to the fact that
i'm asking for everything, but the smsc is only providing certain ones.
i'll get in touch with them about it.
thanks again
