Having been woken at 03:30 by the York car parking system informing me my ticket expired at 04:00 I wondered what controls there might be to prevent similar message from our application?
Clearly we wouldn't be generating messages at such times but I'm aware that delays in e-mail messaging (and perhaps in the network operator's system??) could cause these to happen. Probably there is not a lot to be done once the message has gone to the network operator but it could certainly be possible to do something about the first cause.
Thanks for any comments.
