no, it shouldn't be bounced back.
 
The mta should stop it and report an error to the recieving end, in the same data connection.
 
Bounces are so 90's.

Maybe you have never been jo-jobbed?

Hang on,

A legitimate email is accidentally sent to the wrong email address
because of a simple typo. 

It should be bounced back.

Spam we deal with in other ways.
