Issue/Bug in opensmppbox

Hello all,

We got a ticket from a customer where the sms has not received final
dlr (status still in ACK).

We analyzed our packet trace and we found that our opensmppbox sent
the deliver_sm before sending the submit_sm_resp which leads to
mis-interpretation of the dlr on their side !!.

The deliver_sm was packed with 3 other smpp responses and the same for
the submit_sm_resp but the two were sent in separate packets. And,
deliver_sm was sent before submit_sm_resp.

Any help how we can fix this.

BR.
