I do use spamd (the wraper implements spamc) and because postfix is trying to deliver it to a perticular user, I can easily implement per-user settings (-u on spamc). It's also a bonus doing this at the delivery agent because I don't have worry about not checking out bound mail (As I would have to if I did this with a cf). Frankly any extra overhead due to it being pipe rather than lmtp is dwarfed by SpamAssassin. It's quick n' easy, for me it's the perfect solution ;)
