Extract text from attachments warning in logs

[Know_new]

Hello there

We enabled extract text from attachments option in spam detector menu

Time by time we can see some warnings in logs like this:

see https://pmg.proxmox.com/wiki/index.php?title=Roadmap - the known issues section for PMG 7.3 - you just need to run:
`apt install antiword docx2txt odt2txt poppler-utils tesseract-ocr unrtf`

Hello Stoiko,
Thank you for update
We performed this step as I mentioned above

All dependencies and libraries has installed.

ah - sorry thought you meant that apt is not unhappy about broken dependencies ...

did you restart pmg-smtp-filter after installing the dependencies?
and is /usr/bin/pdftotext indeed an exectutable?

Hello, Stoiko
Thank you for answer

did you restart pmg-smtp-filter after installing the dependencies?
and is /usr/bin/pdftotext indeed an exectutable?

Yes, service pmg-smtp-filter has been restarted and we rechecked twice /usr/bin/pdftotext – it is executable.

Here some new logs:

May be we should increase max size limit for spam, should we?


P.S docx2txt executable too.

Try this in any case - however the error-messages point to the files not being executable/present ...

Do you have any modifications to a plain PMG? - maybe some changes to systemd-unit-files - some other "security" things installed?
could you also check the complete journal of the time the error happens?

Hello, Stoiko
After max size has been increased warning messages disappeared.

And yes, we'd modified PMG in security case - we use custom script for running commercial AV solution.
