I just had a ChoiceMail challenge tagged as spam by SA 2.64 with the
following analysis (apologies in advance for line wrapping that may be
inflicted by gmail):
Content analysis details: (8.7 points, 5.0 required)
pts rule name description
---- ---------------------- --------------------------------------------------
0.7 FROM_ENDS_IN_NUMS From: ends in numbers
0.6 MSG_ID_NO_DOMAIN No domain part in Message-Id header
0.3 NO_REAL_NAME From: does not include a real name
-0.0 BAYES_44 BODY: Bayesian spam probability is 44 to 50%
[score: 0.4459]
0.1 HTML_MESSAGE BODY: HTML included in message
2.9 FAKED_HOTMAIL_DAV X-Originating-Email header does not match From
1.0 FORGED_OUTLOOK_TAGS Outlook can't send HTML in this format
0.0 CLICK_BELOW Asks you to click below
3.1 FORGED_MUA_OUTLOOK Forged mail pretending to be from MS Outlook
I'm not suggesting there's anything wrong with the SA rule
definitions, just providing a heads-up that ChoiceMail may be doing
something stupid. (Independent of whether it's stupid to filter spam
with challenge/response in the first place.)
