Here are a few things I am doing with QS & SA,
Don't know if they are applicable to your situation.

1) In my case the server runs in a small company and almost all of the
emails are delivered to an Exchange Server. I've setup 2 public folders
called SPAM and HAM. The users drag emails in outlook to those folders and
there is a fetchmail script which runs every 1/2 hour on the mail server,
gathers those emails via IMAP and pipes them to sa-learn.

2) We have a rather low score for spam - 4 points, above that the emails
have their subject rewritten to include a SPAM token and then there are
rules in Outlook to put those emails into the users' "Deleted Items" folder
(incase they still want to look at it). Above 8.5 points the emails are
quarantined (I am using the beta version of qs 1.3, by using the ST patch
you can delete emails above a certain score). We have some real emails
classified as SPAM, but not too much, it's a trade off.

3) Beef up your SA configuration. If you have a moderate email quantity (not
an ISP) use RBL and URBL filtering (they work really good) and the razor/dcc
filtering. Also make sure you are using the latest release version of SA.

4) You might want to some custom rules, for instance I have a few rules
which lower the score for specific tokens found in our company email
signatures, so any reply with the original text inside will have less chance
to be considered spam.
Also if have tokens specific to the business of your company, you can add
those manually with a negative score. For instance a cloths retailer might
add "Pants" "Shirt" "Blouse" etc, to lower the score by 0.5 points. (works
good in my case, not those specific words)

5) Make sure your auto white list is working, it helps greatly to reduce the
number of good emails considered spam if you are using a low score.

That's all that comes to mind,
Please share other ideas

Subject: [Qmail-scanner-general]Best practice for QS+SpamAssassin

hello all,

I don't know if this is the right list, but I wonder is there any
information 
about what is best practice in dealing with spam.
My problem is that users get a lot of spam despite of QS+SA running on my
mail 
server. I think that I should run sa-learn, but I cannot get those spam 
messages since they are already delivered to users computers.
So how to catch spam and make SA learn?
