According to Postfix 2.3, patch 10:
20070520
Bugfix (problem introduced Postfix 2.3): when DSN support
was introduced it broke "agressive" recipient duplicate
elimination with "enable_original_recipient = no". File:
cleanup/cleanup_out_recipient.c.
So, you will need to upgrade.
BTW, Postfix 2.3 is no longer maintained. It is almost four years old.
