As described, it is a bug, or filters set preventing the messages from showing. Normal behavior (I just tested) is that if a recipient does not exist, you see:

>> blahblah blahblah: Wut
Tell recipient could not be located. Your message was not received.
>> wutwutwut wutwut: wut
Tell recipient could not be located. Your message was not received.
