-+Example :-
-+[root@linuxbuild exim-4.72-test]# patch -p1 <../exim.dsn.patch-472
-+
-+Expected Output :-
-+patching file README.DSN
-+patching file src/config.h.defaults
-+patching file src/deliver.c
-+patching file src/exim.c
-+patching file src/exim.h
-+patching file src/globals.c
-+patching file src/globals.h
-+patching file src/local_scan.h
-+patching file src/macros.h
-+patching file src/readconf.c
-+patching file src/route.c
-+patching file src/smtp_in.c
-+patching file src/spool_in.c
-+patching file src/spool_out.c
-+patching file src/structs.h
-+patching file src/transport.c
-+patching file src/transports/smtp.c
-+
-+
-+This patch can be included / excluded from the compilation by use of the #define SUPPORT_DSN
-+which gets added into src/config.h.defaults & src/EDITME by the patch.
-+
-+Use
-+---
-+
-+The facility (once compiled in) can be turned on for a particular router via the
-+dsn_process directive Eg :-
-+
-+dest_delivery_int:
-+ driver = manualroute
-+ domains = +relay_to_domains
-+ condition = ${if eq {${lc:$sender_address_domain}}\
-+ {domain.com}\
-+ {yes}{no}\
-+ }
-+ dsn_process
-+ hide route_data = ${lc:${extract{mailHost}{$address_data}{$value}{}}}
-+ transport = remote_smtp
-+
-+Exim will produce 1 of 2 DSN's back to the originator, or pass on the DSN request.
-+The 2 DSN's will either contain (relayed via non "Remote SMTP" router) or
-+(relayed to non-DSN-aware mailer) depending on if the delivery was VIA an SMTP
-+transport or not.
-+
-+

-+
-+12-Sep-2006 : Now supports Exim 4.63
-+
-+12-Sep-2006 : src/EDITME did not include the #define SUPPORT_DSN as stated
-+ in the documentation, this has now been corrected
-+ thanks to Robert Kehl for this information
-+
