 Some Transports now refuse to use tainted data in constructing their delivery
 location; this WILL BREAK configurations which are not updated accordingly.

+Attempting to remove, in router or transport, a header name that ends with
+an asterisk (which is a standards-legal name) will now result in all headers
+named starting with the string before the asterisk being removed.  We recommend

+enhancements, alao header names that look like REs).
