That is a security mechanism. If I can inject a message with a hash that collides with something else in your queue, I can at least prevent you from seeing the original, or potentially spoof a message from someone else.
I know it depends on knowing hashes of other messages in the mailbox, but if the hashes are supposed to persist, that might not be a problem.
