Well, what I did was this: like many people, I'm sure, I've been informed that I've won loads and loads of money in various International Lotteries, and also been contacted by numerous bank officials from African states with intricate ways of getting unclaimed cash out of the country (in return for my banking details), as well as several putative widows of assassinated African politicians. Now, if you press the "Reply" button, but instead of sending this "Reply" directly you then "Save as a Draft", it is possible both to change the "Address Line" and to alter the content of the original message, which will of course appear below one's own reply. So, having first sent the saved, original message to an E-Mail address I set up specifically for this purpose, and then mucked about with its contents, I have both directed some unwanted messages to the senders of other such unwanted message, AND initiated exchanges (from the false identity) with various bankers and widows. I've even had some of them trying to set up meetings with "me"; in fact, I nearly got married to some widowed African Princess...
