The architecture is as follows:
postfix receives all mail -> forwards it to amavisd-new for analysis, if valid the mail is returned to postfix for final delivery (no need to handle stuff in the user end).
If it is spam you can select in the amavisd to forward the mail anyway with a tag appended to it, or store it some place else or just drop it.
Did you bother to read the 2nd link i provided it is the step by step instruction to do exactly what you need to do...
Here it is again:
http://www.ijs.si/software
Please read it and follow it... (ask if you have questions about an item in this howto...)
OK,
What do you want global vs. local checking (ie, in the mail queue, at the end users?)
What is you current config?
We (i at least) cannot read minds, disks without means of access/representation of data. And no I do not want to access you systems to update them.
What exactly did you not understand in the documentation?
The general approach?
Some detail information?
How to edit files?
You can block spam by using a filter that has intelligence in matching spam using various techniques... not just one way.
Some spam uses obvious words,
Some spam uses some kind of phrases
Some spam is sent by mail senders that SHOULD not send mail
Some ....
Too many ways to handle it.
amavisd-new is a product (FOSS), that uses various methods like spam-assassin, virus scanning, blacklist consulting, bulk transmissions of certain content. (razor)
So postfix can do a part (absolute blacklisting, which might block the wrong addresses.)
Or you can install amavisd-new and integrate it with postfix (for instructions see the link in http://#25612313
If you dont want to do THAT, then either learn to live with spam, or use spamfilters your ISP provides OR use a professional filter solution like CloudMark.
You can also buy a barracuda box or likewise boxes which very probably use postfix+amavisd + a few things more effectively doing the same.
There is no easy solution... alas, if you found a more easy solution let me know that would help a lot of people.
compare it to this:
You ask I want to eat ....
I give you a guide to a restaurant
You say I want to eat ... ( i know how to cook an egg)
Then I ask do you want fish, pork, beef or vegetarian?
What kind of vegetable? what for desert etc.
And your still just ask 'i do want to eat.... and i need the recipe too with to the grams specified what the content is'
The problem being that if you might mistype a character and you still wont get what you want
It.s not that black and white i am affraid, there are some question that need to be answered.
Otherwise there is the risk that you end up with a plate of beef, while actualy meant to eat vegetarian... it still is something to eat.
And you will have to make choices, and quite a few of them too you options are displayed inthe referenced URL.,

Try to integrate amavisd-new with postscript.
amavisd can use various (also to be installed) virus scanners, spamassassin, DKIM, blacklisted sites, Vipuls Razor to score a message. Above a certain amount of points messages are considere spam and can be routed to special mailbox, folder or plain discarded.
