    Do not bounce! If the user does not exist, reject the message at SMTP
    time. Problem solved. If you accept the message, it is up to you to deal
    with it. Bouncing will just send messages back to people who don't
    deserve it. Look up "joe jobbed".

    In addition, behavior like that can get you blacklisted.

    Marcin, please do not accept-then-bounce mail sent to nonexistent users or
    mail blocked for spamminess. You may find it increasingly difficult to
    communicate with the rest of the world, and you _will_ be hated.
