Regarding SPAM clearing house?

[gejopaul]

can i install additional clearing houses like pyzor , razor and dcc on DirectAdmin servers. if i install it i think it will catch Spam mails more.
one more doubt I have is I think the bayestian filering is enabled in default installation?

Can I enable these settings for pyzor razor and dcc working properly?
