The file name rule has been configured to filter attachments, but it is not taking action against .msg or .eml attachments. What can be done?
The file name rule works successfully for all configured attachments, except *.eml and *.msg
Symantec Mail Security for Microsoft Exchange (SMSMSE) cannot determine whether a .eml or .msg file is an attachment or a message body during Exchange transport (if attached using certain email clients), and as a result will not take action to avoid quarantining legitimate message bodies.
This problem is fixed in Symantec Mail Security 6.0.10 for Microsoft Exchange and later, including version 6.5. To learn how to obtain the latest version, read Where to download the latest version of Symantec Mail Security for Microsoft Exchange.
