--Local/local_scan.c, and edit the copy. To use your version instead of the
--default, you must set
--
--LOCAL_SCAN_SOURCE=Local/local_scan.c
--
--in your Local/Makefile. This makes it easy to copy your version for use with
--subsequent Exim releases.

--                   writing, but modifying it is dangerous and not recommended.

--  LOCAL_SCAN_TEMPREJECT
