Antispam Classifying Mail As Spam Even From Whitelist Addresses

bigreddog

Running BitDefender Security for Exchange 2.4.214 with Exchange 2003.

I have setup my whitelist to include (amongst others) the entry *@*.nz (get almost no spam from New Zealand domains!). I've been running this for around 18months with no troubles, however very recently I have begun to find mail in the Quarantine from .nz domains. (5 messages this month alone - not sure how many more I've missed).

I've double checked all my settings but can find nothing wrong with them yet 2 more messages in quarantine this morning!

Thanks

Andrew
