How Do I Get Rid Of the @me Version Of My iCloud Email?

I am trying to get rid of my @me email address. Apparently not that easy to do if at all. It is not listed as an alias in icloud mail so I can’t highlight it and delete it. Somewhere along the line the @me version has been aquired by mailing lists and I get endless spam that I cannot control. If I cannot delete this email address from my apple ID what are the best ways to stop the mail from getting to my mac? Is a rule on the server sending spam to trash the best one can do?
