Doing this means that *you* get to see the mail identified as spam, when 
you look in the special file. Rejecting the message in the SMTP 
transaction means that the *sender* knows you didn't get the email, so 
they can either try resending a less-spammy message, or contacting you 
by other means if it's something important. No intervention needed on 
your part.
