Hi folks,
Regrets if this is the wrong list.
Wanted to be able to score on text found in PDF files. Did not see
any obvious route, so made a plugin that calls XPDF's pdfinfo and
pdftotext to get the text that is then scored.
Sample local.cf could be :
pdftotext_cmd /usr/local/bin/pdftotext
pdfinfo_cmd /usr/local/bin/pdfinfo
body PDF_TO_TEXT
eval:check_pdftext("^Error","sex","drugs",'Title:\s+stock_tmp.pdf:4','Creator:\s+OpenOffice.org
1.1.4:4')
Notice that a :4 gives a find of that regex 4 points.
Really don't know if this was the right road to follow, as I copied
the AntiVirus.pm and came up with this:
http://support.ednet.ns.ca/SpamAssassin/PDFText.pm
So far... it appears to work as expected and didn't take down a
pretty busy server ;).
Enjoy hearing any positive criticisms :).
I did this the other day with CAM::PDF, but Theo recommended this work
should be done in the post_message_parse() plugin call. Then you
could just write body rules against the text, uris would get checked
by uribldns plugin, etc....

I did start with keeping it all in Perl, but when I tested my first SPAM
with the CAM::PDF utils, it resulted in just a bunch of space separated
letters :(. Interested in getting something working, I switched to the
XPDF utils. Maybe getpdftext.pl is not a good example of how the modules
work?
Where do I find information on hooking into post_message_parse()? Tried
greping in the module area with no luck :(. Certainly agree it would be
better to get the text out and let everyone at it :). I couldn't see how
to do that when I started down this road. I was even first trying to see
if Exim would add another attachment to the e-mail which would be the
output of pfdtotext, but again, wanted to get something running, so
opted for what is there now :(.
Thanks,
JES
