the DLR storage is completely internal to Kannel and is not supposed  
from the outside.
it is used to track internally messages kannel has sent to SMSC's. The  
DLR url is a callback mechanism to tell your application the status of  
the message. You can not ask kannel for the status of a message, you  
will get informed when the status changes and thats by the DLR URL  
mechanism.

you have to URL encode the URL you put into &dlrurl.

right because &test=.. is not part of the parameter &dlrurl anymore.
