Today I faced a very strange issue. I sent messages 10 days before and on that time smpp were in re-connecting mode. Today when smpp came online then messages are getting delivered. This shouldn't happen. Is there any parameter in cannel which can expire the message after a particular period of time.
I already used validityperiod parameter but it's not working for my case.
Have a look on below issue number and find out it got solved or not.
