Hi!
I enable new option - Extract text from attachments
but when i send test word .docx with bad words inside ... nothing happening.

How can i test if this option: Extract text from attachments running/working?

## my config info ##

can you post the log from that email? what 'Bad words' did you use?

it sill has to match some spamassassin rules that would normally match in the email text too
 
I have custom rules like this:
###
rawbody __PP_LOCAL_UNWANTED_WORDS_16 /\b(crazy bad word 1|crazy2 bad2 word2|crazy3 bad3 word3)\b/i
meta PP_LOCAL_UNWANTED_WORDS_16 __PP_LOCAL_UNWANTED_WORDS_16 >= 1
describe PP_LOCAL_UNWANTED_WORDS_16 Bad word description
score PP_LOCAL_UNWANTED_WORDS_16 7
tflags __PP_LOCAL_UNWANTED_WORDS_16 multiple maxhits=1
###

And this custom rule working perfect for mail text
 
then please post a snippet from the journal where you get that mail, any errors there?

In the log i found other error about PDF:
Apr 13 17:34:37 mailgw pmg-smtp-filter[211415]: WARNING: extracttext: error (99) from /usr/bin/pdftotext: Syntax Error: Invalid XRef entry 3
 
i thought it was a docx?
is that log from the tracking center or journalctl/syslog? (please post from the syslog/journal

the warning seems to say that the pdf is probably malformed and can't be parsed, so it cannot detect the text ?

Click to expand...
When i`m sending some test .docx nothing showing in syslog ...

But i found other mail sender ...
So i found this errors:
Apr 13 16:32:03 mailgw pmg-smtp-filter[201124]: WARNING: extracttext: error (2) from /usr/bin/docx2txt: Failed to extract required information from </tmp/.spamassassin201124ouN1xTtmp>!
#
Apr 13 10:19:31 mailgw pmg-smtp-filter[15057]: WARNING: extracttext: error (1) from /usr/bin/tesseract: Premature end of JPEG file
#
 
well i guess the specific documents and images are simply not properly parseable/scannable by the tools that are in use, i guess we cannot really do anything about that from our side
you could try to report errors with the faulty documents to the respective projects (docx2txt/tesseract/pdftotext/etc.)
 
On a hunch - how large are the files you're trying to scan - and what is your Max Spam Size setting (GUI->Configuration->Spam Detector->Options)?
