F-Secure Protection Server blocks PDF attachments

 

Hello, 

 

I have the followinf problem:

 

F-Secure Protection Server ®  - Version 6.0,  blocks incoming emails that contain PDF files. Not all PDF files are blocked, but only the ones that contain a special attachment inside the PDF file - a file with extension .joboptions . Thsi file is generated whan the PDF file is created by a user in a remote company and is not a virus.

 

The Reason for the block is "AV: corrupted"

 

Is sais that the triggered rule is "module.av.rule.error", but this seems to be a system rule.

 

My question is: How can I create a rule that will not block such files?

 

If I whitelist the domain, the problem is solved, but I need to be able to receive such files from any domain.

 

Any ideas?

 

Thank you.
