When Symantec Messaging Gateway (SMG) has language identification enabled and is configured to block Chinese messages, some messages with Hebrew or Arabic text are deleted. This may include other character sets, but known cases have involved only Hebrew or Arabic text.
This issue has been corrected in version 10.5.0 of the Symantec Messaging Gateway. Please update to Symantec Messaging Gateway version 10.5.0 or greater to include this correction.
