Lee - i set up spam filters several times. every time, at least one really important email found its way into the spam to be thrown away.

and a lot of people who say that never happens have had my emails go into the spam area when they told me they didn't get my email...

so now i eyeball every email by sender and subject - luckily i read very fast. it does take up a little time, but i haven't had anything disappear since.
