If you use Yahoo Mail service for your daily email services and get lots of spam bulk email, there is a good service to combat spam emails, provided you upgrade to Yahoo! Mail Plus.
With AddressGuard, you can easily create alias disposable email addresses to use on websites or public web services (when you don’t want to give out your primary Yahoo! Mail address) and direct incoming messages to your Inbox. If an alias email starts receiving spam email, just delete it and create another new email address.
And Yahoo! Mail Plus also gets you 2GB storage space, personalized spam filtering with personal “smart” filters in SpamGuard Plus, 20MB message size, no graphical ads or promotional taglines and the ability to download your email messages from any POP3 account using an email application like Outlook.
