You could let your Email Provider know. Although they probably won't be able to do very much about it. Spammers collect email addresses and then include them as the return address in the emails they send out. The body of the email contains the damaging links so the email address is completely superfluous except to try and legitimise it. In the early days of the Internet, it used to happen to me a lot - but I changed address a few times and don't put my email address on public display for it to be retrieved and used.
