Continuing the spammer's march to make sure that e-mail is 100% useless soon, I recently received a spam with this title: "Please return immediately, or we will be forced to take legal notice". Can you afford to ignore that, in light of the fact that electronic notice is sometimes sufficient, IIRC? (Though the last word should be "action".) It's a porn spam.
It is getting harder every month to visually scan my spam and reliably seperate them by title.
