So at the very least it came through Yahoo's servers. The fact that it was sent to addresses in his address book (not just this one, as I understand it) suggests that they have had access to his account. Btw, I created a Yahoo account myself and send some emails to other addresses of mine. They all come with a X-Mailer: YahooMailWebService header; in fact the headers are the same as the email that started this discussion. So we can't conclude they used Yahoo's API. Martijn.
