I've dropped .js, .html, and .lnk as top level extensions from those signatures as they were causing too many problems.

I really appreciate your patience and communication while we fine tune these. They're covering a lot of email borne threats, and if that is not your use case, white listing is a great option. Let me know if you are still getting alerts that are problematic.
