Mail security is not able to scan hqx files.

Hi all,

*.hqx Machintosh files BinExe are detected like unscannable.

I tested several messages with the attachment and I got the following error from Symantec Mail Security for Exchange version 6.0.11 :
 

"2.jpg.hqx" located in message with subject "xxxxxxxx xxxxxxxxxx", located in SMTP has violated the following policy settings:

                Scan: Auto-Protect
                Rule: Unscannable File Rule

The following actions were taken on it:
                The attachment "2.jpg.hqx" was Deleted for the following reason(s):
Scan Engine Error.  CSAPI DEC result: 0x15. Decomposer failed to extract the file from a container.

At the moment if I disable the action to quarantine Unscannable files and moved to: Log Only + disabled Autoprotect it works normally, but obviuosly there is a concern about the security.

First solution:
Convert the file in jpg before to delivery the file to the Symantec server.

Second workaround:
Set quarantine for unscannable and release the files manually as files.

third workaround:
Set log only for unscannable files. (Not suggested).

The same issue has been reproduced in SMS for Exchange 6.5 and Symantec Brightmail Gateway version 9.x since the error is trigered by the decomposer.
Also most of the operating systems are not able to open the file. Moreover if the file is received cannot be opened. The enduser should convert the file in a standard format using a tool in order to open it.

It would be nice to have a decomposer capable to decompose the file since it is a good file. It will be user responsibility to open the file then.

regards
Christian
