FYI: I had to bump my TimeValue parameter all the way up to 96 hours in order to get an e-mail from that "Test Notification Policy" button. However, have yet to confirm whether the policy will automatically fire off an e-mail to me the next time MS releases updates. Figured was good time to test because Patch Mgmt didn't show MS10-002 yesterday but did today although I got no message with my TimeValue previously at 72 hours. I'm thinking my TimeValue could be a bit smaller since my pmimport occurs AFTER my new bulletin check but what still isn't clear to me is why I have to put in such a large value when the patch was released just the day before? You'd think 24 to 48 hours should cover it but even at 72 hours, I never got an e-mail alert. Luckily this issue isn't critical where jharings' comment on subscribing to the appropriate Altiris KB is actually a good suggestion.
