Buy and use a spam filter, or use the ones provided by your ISP to filter the spam into a Junk Mail folder. You can also use Outlook to create Rules to block by content--- go to the Help tool and search for Rules. You really can't stop them from coming--- once the spammers know your address is valid, there is not much you can do. The link below will tell you some good tips for not getting on those lists in the first place.

Well, stop posting your email addres to the internet like you did in the question!!!  It makes it very easy for spammers to harvest.\n\nSet up a filter in your email service that sends spam to a junk/bulk folder so you don't have to see it.  Most email software allows you set either set filters or block address/senders.

On your Yahoo Mail page, Click on Options in the upper right corner.  Then look for POP Access and forwarding.  You will see options WHEN DOWNLOADING MESSAGES.  Select the option that saysI don't want to receive any messages that SpamGuard thinks are spam

>In Yahoo Mail "which is what I use" I don't think you can stop spam.I have tried.At least they put it in the Bulk folder and messages in your Bulk folder do not count toward your mailbox storage quota.You can delete them if you want or Yahoo will automatically delete them after thirty days.You are supposed to be able to unsubscribe but it didn't work for me.The more I unsubscribed the more I got.Changing your email address is probably the only way to stop it,and then only for a short while.

Depending on how much spam you really are receiving you could either do one of the following.\n\n1) Click on the (unsubscribe) link at the bottom of each of your emails and unsubscribe yourself from their mailing list. That is assuming their is an unsubscribe link which their technically should be! This method might take some time and is not guaranteed to end all mailings but might be worth your try.\n\n2) Just get a new email address and slowly start to direct all important mail to that new address until you can eventually just delete your old spam ridden one. Try to make sure that you pick an address that is not easily thought of so you dont end up with more spam down the road. And last... make that address the one you DO NOT GIVE OUT online eg. web forms, opt in forms more info forms etc.. Try creating a seperate email address for that type of stuff.

These type of complaints should go to abuse@yahoo.com\nQuote the entire message including the email headers which are very important. Yahoo is usually pretty good about shutting accounts down that send spam or 401 fraud messages.

Sounds like someone running a scam.  They offer you a % of a multi-million dollar amount?  Delete the e-mail, record it as spam and go on about your business.

Forward them to "abuse@yahoo.com" and delete them as spam.  Also, never reply to the link in an email that requests passwords or to verify account information.  Access the website directly to be sure that you are interacting with the real deal instead of a phishing expedition.

There is NOTHING you can do to prevent SPAMMERS from sending their CRAP,\nYou can only be diligent in setting up domain blocks and content filters that delete/move the incoming emails to the trashbin (or other preselected folder) upon arrival.
