For anybody who requires DSN support for Exim :-
Latest patch is available at :-
http://sourceforge.net/projects/eximdsn
It now supports Exim 4.60
Changes (Exim-4.60 & back tracked to Exim-4.52) :-
Now produces DSN's for any email delivered locally or via pipe/redirect
router rather than just SMTP delivery.
Problems with running on Solaris fixed - kept producing seg faults due to
differences in the way Linux & Solaris handles NULLS.
