Got an interesting variation on those "Strong Buy!" stock scams.
Instead of a straight message, they'd taken a screen shot of the pitch
and rotated it slightly (presumably to make CR more difficult), then
placed the image in an email.
And yet check out the score it got:
Message scored 14.2 points, 5.0 required;
* 1.1 SPF_NEUTRAL SPF: sender does not match SPF record (neutral)
* [SPF failed: Please see <URL_REMVED>]
* 0.1 HTML_90_100 BDY: Message is 90% to 100% HTML
* 1.6 HTML_SHRT_LENGTH BDY: HTML is extremely short
* 0.0 HTML_MESSAGE BDY: HTML included in message
* 4.0 BAYES_99 BDY: Bayesian spam probability is 99 to 100%
* [score: 1.0000]
* 0.0 MIME_HTMLNLY BDY: Message only has text/html MIME parts
* 3.6 HTML_IMAGENLY_04 BDY: HTML: images with 0-400 bytes of words
* 0.2 MIME_BASE64_NNAME RAW: base64 attachment does not have a file
* name
* 2.5 FRGED_THEBAT_HTML The Bat! can't send HTML message only
* 1.1 HTML_MIME_NHTML_TAG HTML-only message, but there is no HTML tag

All I can think of is that they're attempting to evade another anti-spam
product, one that uses CR, but is secret/proprietary hence *we* don't
know about it.
I don't dare to hope that this could be my program SPAVI where I added an
CR feature already in 2005.
Unfortunately SPAVI is rather unknown since it is an online program and I
can not publish it on all those free software pages.
