It's your own e-mail program, not your computer, that diverts them. If you have the Yahoo premium service, be on the lookout for MTF messages in your bulk folder each time you check mail for a while, then open and click "not spam" for each message. Since you're on Yahoo.com, which has done the same to me, esp w/out-of-country messages, try writing to Yahoo customer service, but they're notorious for not replying, or asking you to purchase a higher-priced service. I guess "reports of my Mark Twain Form mail being spam are greatly exaggerated" is the smile of the day.
