So do all the major email programs. Before I got smart and started using Yahoo mail for all my non-personal Internet communications, I used the filters to block spam and it worked pretty well. The filters work more or less the same way in every program.
You will have the option to automatically delete emails with certain keywords in their subject line or body. Popular spam keywords are "porn" "free" "win" - stuff like that. You can browse your spam to figure out which words will work best for you. Of course, there's always the possibility that a legitimate email has one of those words, so instead of having the program automatically delete the potential spam, it's best to create a "Junk Mail" folder and when you have some free time, give it a quick look to make sure nothing important got put in there. If something legitimate was mistakenly identified as spam, you can always create another rule specifically allowing that particular sender to bypass the Junk Mail folder in the future and go directly to the Inbox.
Another trick is to create a rule that allows you to receive messages only if your email address is in the To or CC field. A lot of spam does not have your address in those fields, so they'll go directly to the junk Mail folder.
Finally, if all else fails with a particular spammer, you can create a "Block Sender" or "Block This Address" rule specifically naming that sender. This will block any mail from that particular person or domain who sent you the message.
No filter or Spam Blocker is fool-proof. You may have to tweak the rules and settings a bit in the beginning until you get the results you want.
