Email spam

I’ve just determined that Apple is not capable of controlling email spam through their servers. Although I have received a great deal of support from Apple technicians, they do not have a method of stopping these spam emails before reaching me.

My situation is that I have been receiving numerous spam emails using an email address with random numbers and letters as part of the address, but always includes a constant “savethekoala.com” as part of the address.

While Apple apparently is able to provide email rules that can detect and block content within the email message, they cannot detect and block text in the senders email address. As a result of this I am left blocking messages, sending them to “junk” and then deleting them.

My preference is to have these spam emails caught by the server and deleted before they reach my email.

Any suggestions on how this can be accomplished?
