F-Secure Email and Server security strips random xls files
We are running F-secure Email and Server security premium on 2008R2 , exchange 2010 server.
For some reason, random .xls files are not coming trough.
When I check from web console Email traffic scanning -> strip these attachments -> edit, the .xls extension is NOT listed.
When I check FIle Quarantine, there are no items quarantined.
When I check Email Quarantine -> query it says "Disallowed attachment" for the mails that contained the .xls
We had this problem (couple of montsh?) before. If I recall correctly then the attachments was atleast found on the quarantine. I was told by F-secure support that the problem had been fixed.
Any idea how to fix this?
