Mandriva /postfix - Spam Filter

[mhagelstrom]

I followed the instructions to have a spam filter for my exchange box. The emails are getting into the postfix but they are never sent into the exchange.
The only difference I have with the how to is that I don't have an Active Directory so I skipped that part and changed main.cf as not to limit the receivers.
How can I debug as to check where I'm having problems? Is there any kind queues? I tried to read some logs but didn't find any useful information. I'm a newbie in postfix so I'm a little bit lost.

Thanks in advance

I could solve it! My main.cf had a couple of lines repeated.
New Question: How can I keep Clamav updated?? I have to run a cron job or something?

Do you have freshclam running? freshclam updates your virus signature database.
What's the output of ps aux|grep -i clam?
