There are two safe workarounds: 1) Forbid the use of Microsoft Windows. That works for Roaring Penguin. It is unlikely to work for most installations. 2) If you see a MIME part of type message/rfc822, then rather than blocking it, just rename it to something innocuous like "message.eml" and rebuild the MIME message. See "action_defang" in the mimedefang-filter man page. I've heard rumours that if Windows cannot determine what to do with a file based on the MIME type or file name, it actually looks at the "magic values" in the file to determine the file type. If this is the case (I have no way of knowing), then the only safe workaround is (1).
