Spam filter

Presuming you're using the Yahoo webmail interface, you can't.  Yahoo controls all of the parameters and does not provide users with any tools/settings to change a thing.  Yahoo has the worst spam filter of any of the free email services and it's not even close.

Well, bummer!  It used to work quite well for me until lately.  Maybe the spammers are getting better at hiding it.

Thanks.

Everyone being “spammed” by yadoo and at&t should start forwarding all of their spam or junk emails to abuse@att.net so that at&t can get the yadoo email spam experience that the herd is having daily.

maybe when they start receiving millions of spam emails a day, they will either fire yadoo or fix the problem.

Excellent idea!  I love it.
