Increasing Spam arriving at my icloud.com/me.com Address

Recently the volume of spam arriving at one of my icloud.com/me.com email addresses has increased dramatically. Beyond the manual managing of junk filtering in Apple Mail for desktop, are there any other tools available to icloud email users that will help eliminate junk mail?

In my experience, the icloud/me/mac.com email service has not historically been prone to this problem, so it seems like something new. Hopefully this does not indicate a decline in the service.

Any feedback is much appreciated.

Thanks, Dan
