Vinh,

Please note that there are cases where SpamFilter will lock email but not quarantine it. An example is if someone from Yahoo.com tries to bounce an email to microsoft.com using you server. Obviously you do not own microsoft.com, so the email should never be accepted by your server. In this case, there is no need to quarantine it, and it's rejected immediately.

If you say you "are letting everything through" then most likely you indeed are, and nothing will be quarantined. There will be always rejections caused by the above explanation (relay attempts using your server) that won't get quarantined.

Unless you configure some filters to actually begin blocking something there will not be a way to test if your quarantine database is working.
