Yahoo catches five-fold increase in filtered e-mail spam

Yahoo Inc. filtered out five times more e-mail spam last month than in February 2002, but the company says it`s committed to working with retailers and other advertisers who believe their e-mail was unfairly blocked, Yahoo tells InternetRetailer.com.

Yahoo Inc. filtered out five times more e-mail spam last month than in February 2002, but the portal company says it`s committed to working with retailers and other advertisers who believe their e-mail was unfairly blocked, Yahoo tells InternetRetailer.com.

Yahoo uses an in-house SpamGuard filtering system that automatically detects and filters inbound spam into a Yahoo Mail subscriber`s personal bulk mail folder, a spokeswoman says. Yahoo systematically places in the bulk folder certain types of e-mail widely recognized as spam, but it allows a user to create up to 15 customized filters to direct mail into personal folders. Yahoo Mail Plus subscribers can create up to 50 customized filters.

 

Users can also send personal input to the SpamGuard system by clicking on links to identify bulk folder or in-box messages as either spam or acceptable e-mail. "The feedback we receive from these links plays an integral role in our continuous improvements to the SpamGuard system," Yahoo says. "Users are able to customize their spam-fighting efforts by blocking addresses, setting up customized filters and blocking HTML messages."

In addition, marketers can directly appeal to Yahoo`s customer service department if they believe their e-mail promotions are being unfairly filtered into the bulk folder.

Yahoo says it constantly upgrades its SpamGuard system to deal with the unceasing efforts of spammers to get around its filter. "Our team is constantly monitoring the various techniques spammers are employing," the spokeswoman says.
