since upgrading to newest version of spam sieve and OS X yosemite, I have been getting tens of old spam messages and notifications appearing in my spam box. Some are from 2013. When I had notifications turned on with growl, my screen filled up with “questionable” spam notifications and the faster I deleted them, the faster they popped up. I turned off the growl and not getting mass notifications, but I am still getting old deleted messages from somewhere.
Any one have an idea how to stop this?
