junk mail from Russia

Hi, I am in a  quandary regarding email I keep receiving, apparently from my own email address but the link is http://swissdeluxe.ru.com which is on the bottom of the email. No matter how many times I try to block this, it still keeps coming into my junk folder. How can they use my email address to send junk mail to me and is there a solution to this problem. Any help would be appreciated. ps. I have blocked all email addresses from russian sources so this isnt working. Cheers, Ron.
