--This file contains a template local_scan() function that just returns ACCEPT.
--If you want to implement your own version, you should copy this file to, say
--Local/local_scan.c, and edit the copy. To use your version instead of the
--default, you must set
--
--HAVE_LOCAL_SCAN=yes
--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.
--
--For a full description of the API to this function, see the Exim specification.

--/* This is a "do-nothing" version of a local_scan() function. The arguments
--are:
--
--  fd             The file descriptor of the open -D file, which contains the
--                   body of the message. The file is open for reading and
--                   writing, but modifying it is dangerous and not recommended.
--
--  return_text    A pointer to an unsigned char* variable which you can set in
--                   order to return a text string. It is initialized to NULL.
--
--The return values of this function are:
--
--  LOCAL_SCAN_ACCEPT
--                 The message is to be accepted. The return_text argument is
--                   saved in $local_scan_data.
--
--  LOCAL_SCAN_REJECT
--                 The message is to be rejected. The returned text is used
--                   in the rejection message.
--
--  LOCAL_SCAN_TEMPREJECT
--                 This specifies a temporary rejection. The returned text
--                   is used in the rejection message.
