Once again I've managed to get spam on a new machine, with an e-mail address that I've only ever used to send to the lists. Is this hotmail mob that spam people the same lot that offer free e-mail accounts? And is it possible that they somehow examine all the headers of mail sent to any of their "free" users in order to increase the size of their spam lists? Like, if I send mail to the list and one of the recipients uses hotmail could I then manage to get myself of the spam list?
