Just tested it by sending a message to someone from Reddit. They must not be on though, no reply. My understanding is that eventually, if he does not reply the message vanishes?
I believe so, but then it retries every few days - think I read that somewhere. You don't have to send the test message to an actual person. There is an echo server or the like that I saw on the instruction page. Just send it to that and you should get a reply in 4 minutes or the like.
