When blocking .eml attachments with Symantec Mail Security for Microsoft Exchange running on Exchange 2007 using the "File Name" rule, the .eml files are only partially stripped
Last Updated January 08, 2014
The "File Name" file filtering rule is configured to block the term *.eml
The notification email sent to the user does not contain the information configured in the notification section of the rule
The "quarantined attachment.txt" sent to the original recipient contains scrambled header information from the original message
In Exchange 2007 the content-type of attached .eml files is "message/rfc822". When Symantec Mail Security for Microsoft Exchange (SMSMSE) replaces this file according to file filtering rule, it changes the name of file to "Deleted Attachment.txt" but it doesn't change its type to"text/plain" from "message/rfc822".
