Description:
The attachment "sheet1.xlsx" located in message with subject "Weekly Details", located in SMTP has violated the following policy settings:
                Scan: Auto-Protect
                Rule: File Name Rule
The following actions were taken on it:
The attachment "sheet1.xlsx" was Quarantined for the following reason(s):
 UNAUTHORIZED FILE was found in printerSettings1.bin within printerSettings within xl.
 UNAUTHORIZED FILE was found in printerSettings2.bin within printerSettings within xl.
 UNAUTHORIZED FILE was found in printerSettings3.bin within printerSettings within xl.
 

MS Office 2007/2010 Files contain .bin files, as Mail Security decomposes the file it finds the .bin extension files
and quarantines them if the File Type is added to the Match lists with File Name Rule
All Microsoft Files are seen as container files by decomposer. Also applies to PDF Files.
This is by design. Also .BIN extension is not added by default in Match Lists in any SMSMSE Versions.
