Affected module: brightmail_engine
Product version: Symantec Brightmail Gateway 9.0 and later versions
In addition to this error, the following error is likely to appear:
 Gatekeeper module: Test message: MD5 signature is NULL
This error message occurs when you attempt detection of messages by using content filtering based on file metadata, and the message being scanned has an attached file that cannot be examined such as an encrypted file or an incomplete zip file.
No action needs to be taken to address this problem. Only those message parts that cannot be opened are bypassed in the scanning process.
You can also upgrade to Symantec Messaging Gateway 9.5 to resolve this issue.
