    Does gmail use baysian filtering? Perhaps you don't get much. I have
    heard this below gets 92% with minimal false positives:

    http://www.spamhaus.org/effective_filtering.html

    I have yet to establish what system my ISP uses. The emails come through
    with email headings such as:

    X-RBL-Warning: yes
    X-RBL-Warning-Info: warn.bl.kundenserver.de says: Dynamic IP Addresses
    See: http://www.sorbs.net/lookup.shtml?24.147.79.153
    Envelope-To: adam.hardy@cyber.......
    X-SpamScore: 0

    But I don't know what puts the headings in.
