Wrong magnetization with "message deleted"
Explanations:
(first queue of messages) If we delete a message 10 min after sending it, the magnetization will not be the good one.
(second queue of messages) If we delete the message within the 10 min, the magnetization is correct.
To resolve it, the timestamp of the message deleted should not be changed (keep the same timestamp as before deletion).
