Can you point me to exactly what is leading you to conclude that the message is littered with fake virus warnings?

 

I see the X-MDBadQueueReason header which says the message is infected with virus (completed-transcript-0E37323141.pdf). I can see where this could be confusing. Unfortunately this cannot be customized.  We will look into improving the wording for a future version.

 

Is there other information that is included in the message that is leading you to believe the message is infected?  Or is it just this one header? 

 

The body of the message states multiple times that the message was not able to be scanned:

 

SecurityPlus for MDaemon was not able to scan message attachment

The message has been scanned by SecurityPlus for MDaemon and was found
to contain an attachment that could not be scanned. Information on the
attachment and action taken is provided below.

If you don’t like the messages included in the body of the message, they can be customized to fit your needs.  To do this go to Security / AntiVirus / Virus Scanning, then click the Warning Message button next to “Add warning to top of message body if not scanned.”

MD occasionally fails to scan a PDF file and then says that it contains a virus although there is zero evidence for this, and in the example below that was stopped this morning, I think that it is extremely unlikely, I suspect that the PDF is simply images because it's not password protected, it was downloaded from an academic site, processed by the users Windows 10 AV software, and then stopped by MD.

I would rather see MD tell the truth, that the document can't be scanned and is held, rather than littered with fake virus warnings.

>A password protected PDF can't be scanned 

You are correct.

I'm not sure what you are wanting to be changed.  Are you just wanting to allow files that cannot be scanned to be delivered?  If you do go to Security / Antivirus / Virus Scanning, uncheck the box for Quarantine messages that cannot be scanned.  Or if you prefer you can allow password-protected files based on sender, recipient, and file name.

You can also add a warning to a message that was not scanned, instead of quarantining it and the message is customizable.  To enable this check the box next to Add warning to the top of the message body if not scanned, and then to customize it click the warning message box to the right of the item.

A password protected PDF can't be scanned - MD needs to simply tell people that the PDF attachment was not scanned, not assume that it was a virus although that's certainly a possibility, I'm not going to open a password protected "New $10million PO.PDF" (LOL) but I will open 2022taxreturn.pdf once I verify that it was sent from my accountant in the US.

Maybe the "unscanned" message could add some basic details about the potential source of the unscannable emails?
