- update to exim 4.94
* some transports now refuse to use tainted data in constructing their delivery
location
this WILL BREAK configurations which are not updated accordingly.
In particular: any Transport use of $local_user which has been relying upon
check_local_user far away in the Router to make it safe, should be updated to
replace $local_user with $local_part_data.
* 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.
