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 at domain),  the  lookup  order becomes: user+foo at
domain,
       user at domain, user+foo, user, and @domain."
