    So what is a "text box"? Might that be a graphic image inside an
    HTML-formatted e-mail? If so, nope, your e-mail client's rules cannot
    search inside the graphic for words - because there are no words inside
    a graphic (how you interpret images within the graphic as words does not
    make them such). Your e-mail client may let you score or tag e-mails
    that certain filetypes for attachments or MIME parts within the body -
    but then you never bothered to mention WHICH e-mail client that you use
    (so someone familiar with it could tell you if searching on MIME headers
    within the body is possible with whatever e-mail program you happen to
    use).

    Yes. Use additional filtering strategies that aren't words, IPs and
    structures.

    Filtering only on the words of a spambody will miss the items which
    don't have any spammish words or word-like strings because the spamwords
    are in a graphic only - not words.

    SpamPal uses filtering for the IP addresses which source spam, which is
    a completely different principle than spamstrings. It also uses regular
    expressions on /structures/ of the mail which aren't spamstrings.

    Practically all spam will come from different IP addresses and FROM:
    addresses. Spammers (known to be stupid) are smart. They are relaying
    their crap from the compromised computers of millions of clueless home
    users, each of which has its own IP address. They also almost always
    either use a victim's address in the FROM: or their spamming software
    just makes up an address.

    Trying to filter on IP or FROM is a worthless endeavour.

    The way SP SpamPal works is by using the IP addresses which are found in
    numerous spamsource db/s databases -- I don't 'manually' enter any IP
    addresses like you are describing for Tbird. That won't work. Also,
    ignore the From.

    Also, the way you have your newsagent configured to both have short line
    lengths as well as an unconventional cite mark of " -->" or "space dash
    dash right single guillemet" instead of simply using the right single
    guillemet like everyone else -- causes the lines which you cite to be
    'chopped up' into very very ugly shortlines.

    I recommend that you configure for linelengths somewhere around 72-74
    and that you use the conventional > right single guillemet space for
    your cite or "quotation" designator.
