Which would be better done using something like spampd or amavisd-new and/or using Postfix advanced content filtering of course...
Actually I know what I'm doing and I'm quite happy with it. 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 ;)
And if one is happy and things are working one should stick with it of course. :)
I was just trying to point out that if you're handling a fairly large amount of e-mail and from Postfix are calling wrapper+spamc+running spamd+deliver chances are you wouldn't be that happy. ;)
