Hi,
My distro is still running amavisd-new-2.10.1-6 and I am having issues
with some Microsoft Office documents. I have blocks for .bin and .zip
attachments but nothing for .xlsx/pptx/docx and some xlsx files are
being tripped up by the zip filter. I have read that I can whitelist
them with:
[qr'\.(xlsx|docx|pptx)$'=>0]
in the $banned_filename_re parameter rather than allow zip files. I've
tried searching and have not been able to work out the different options
for the "=>0" bit of the parameter.
Does this approach have an disadvantages? Does it just mean these files
will not be blocked but the rest of the message will be checked and
these files will still be checked for viruses or does it have wider
reaching consequences?
Regards,
Nick
