reviewing your kannel.log unveils the cause:
Here is the deliver_sm PDU we get from Logica's simulator:

Octet string dump ends.
SMPP PDU dump ends.
note the esm_class = 0x00, this is the field indicating the ESME (Kannel) what
kind of "type" this MO is. A DLR would have specific bits set in this field, see
the SMPP v3.4 spec for the esm_class.
Ergo: It's a misbehaving SMSC here... Keep in mind, this is a "simulator". Seems
like the Logica guys didn't take care of doing it the right way for the
simulator as they do it generally for their real SMSCs ;)
