Could it be postfix's cleanup / trivial-rewrite getting in the way and rewriting headers ?

Do you have propagate_unmatched_extensions turned on?
http://www.postfix.org/aliases.5.html shows that has to be on otherwise it could drop the +detail part... On my machine it is by default set to
propagate_unmatched_extensions = canonical, virtual
According to man pages, the behavior of these values (canonical and virtual) in this regard seems to be identical:
" When a mail address localpart contains the optional recipient delimiter (e.g., user+foo@domain), the lookup order becomes: user+foo@domain, user@domain, user+foo, user, and @domain."
