Spam Filter

I was explaining to my mother in law that Apple's Mail program has a built in spam filter that learns what the owner classifies as spam. I know it's not new technology, but it is to many people who switch. Most people just aren't used to having built in spam software. She was amazed when I told her that she wouldn't even see most spam in a couple weeks because the filter will get rid of it before it hits her inbox. She's becoming more and more happy with the switch (not that I had any doubt!). My mom can't believe that it's hard to keep a Windows machine working well, but she doesn't understand that with a Mac it can be done without any effort.
