If the A/V software on the mail server is unable to detect malware in an
attachment, but the filename extension is in our list of dangerous
extensions, we append '.unknown' to the filename, and insert a MIME part
at the top of the message advising the recipient that he/she should not
open unexpected attachments. But some folks do it, anyway. I used to be
surprised at that behavior, but not anymore.
