In pop3 protocol, fetchmail does not download the mail headers and
body separately. This is because, the pop3 protocol does not allow
download of the body of a mail separately. So, even if the mail has
been refused, fetchmail still downloads the rest of the body.

To avoid downloading the body, you will have to:
- use imap instead of pop3,
- set postmaster to "" (empty).

Note that if you set postmaster to "", you may not get any
notifications from fetchmail.
