[Exim] DSN in Exim

Hello!

Does Exim support Delivery Status Notification, as described in
rfc1891 and rfc1894? When using EHLO in SMTP negotiation, it doesn't
answer DSN and Netscape reports "Your SMTP server doesn't support delivery
status notifications..." It is not good, as for me. I wrote small script,
which checks for Return-Receipt-To header in message (it starts in
shadow_transport when local delivery finishes), but it is rare event when
somebody uses this header for delivery notification. Is it possible to
make Exim to work with such requests - without source code changes?

Thank you.
