Home Forums Networks & Cross-Platform Networking Junk Mail Filtering-Apple mail

I have a persistent piece of spam that keeps changing a series of digits to make it look like it's a different source each time. I noticed there is a common part of the address script consisting of 6 digits and the first part of my email address: "332248.myname@". If I instruct Apple Mail Rules to delete "332248.myname@" on arrival, Mail Rules asks if I wish to apply it now and it will immediately get rid of the message. However, Apple Rules allows it in the next time it shows up.

Apple Rules has an Advanced feature with considerable fine-tuning of the 'go away' criteria and I'm thinking it may be a better approach. Any cautions?
