Speaking of typos and security, I just realized that a spell checker wouldn’t have caught that goof. My old lab-mate Shawn would never touch a spell checker, because he said it bred a false sense of security. I feel the same way about spam filters. A carefully trained filter might catch most if not all of the spam, but eventually you’ll lose some false positives on a binge delete of those thousand odd dead messages that piled up while you were off doing more-fun things. As much as I dislike clearing spam, I dislike losing email even more.
