TBB suggested adding tokens from the mime headers to the mix as a way of
maybe getting more useful tokens. I have not tried this myself but
thought I'd pass it along for anyone who wants to. You might try
something like this:
spamprobe -o suspicious-tags -H+content-transfer-encoding \
-H+content-type -H+content-id train
(note the \ to wrap in the right place - really it's one command line)
Not sure if the headers will help or not but they might be useful. My
intuition is that the tokens from these headers are likely to be pretty
neutral if spammers are smart enough to randomize file names and
attachment ids.
On the subject of how spammy inline images really are: in my database
terms containing cid have the following data:
0.8337588 388 8854 1 U_cid
0.9721581 31 4925 1 Timg_cid
0.9721361 31 4921 1 Timg_src cid
So it seems that cid is a good spam indicator but not a perfect one for
my own email.
All the best,
++Brian
