So basically what you're basing this comment on is the fact that you sent a test spam message to your server and it got dropped? What would you have expected it to do? Anything that's spam will get dropped, anything that's possibly spam will go in the Junk folder - that's the way it works.

I have only the following set:
Hostname in greeting violates RFC (reject_invalid_hostname)
There are many misconfigured mail servers around and setting the DNS & Protocol check be too aggressive will get a lot of valid email rejected.
With those settings I see very little spam on my system, probably around 10 messages per month in my Junk folder and the rest of the spam gets dropped.
