Sorry - you wanted to know how we deal with such attachments. For me, ASSP_AFC marks them for a sandbox system for analysing and let them all pass. The sandbox system extracts all attachments to their atomic parts, let some windows VM's open every single part or attachment and analyses every VM memory for malicious code and actions. The sandbox system has ~600 blocking rules and several thousand scoring rules. If an attachment is classified as bad, the mail is moved to a quarantine for manual investigation.
