-+Example :-

-+
-+Expected Output :-
-+patching file README.DSN
-+patching file src/config.h.defaults

-+
-+
-+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.
