I've had this problem since the early 12.1 versions.
I am currently running Symantec Endpoint Protection Manager 12.1.6 build 6860.6400 on W2K8 R2 SP1.
If we create a new .docx file that is about 27K and send it out on an email, it immediately triggers this error:
Location of the message: Action Auction/Sync Issues/Conflicts Sender of the message: MAILER-DAEMON Subject of the message: Undeliverable: CET Action Auction
The attachment(s) "2016 New Donor Packet A .docx" and/or the message was Logged Only.
This was done due to the following Symantec Mail Security settings:
Scan: Auto-Protect
Rule: UFR - Malformed Files

The same thing happens with small PDF files we create and send out. It's annoying to the end user when they are constantly receiving these error messages only to find the email attachment was successfully delivered.
When I enable background scanning, my administrator mailbox gets deluged with hundreds of these errors for benign pdf and docx files.
What can I do to stop this?
