You're assuming that the filterer is silently discarding the message and not
bouncing it. If a site is blocked from sending mail via MAPS or any other
method, the receiver must send a bounce message to the sender to avoid
breaking SMTP.
Assuming the filterer is not breaking SMTP by silently discarding messages,
Bob will receive a message saying that his message couldn't be delivered,
with an explanation.
