Friends of mine a couple states away, on dial up, recent switch to Yahoo, are able to receive email but not send any. (Were able to when they used I.E. / MSN, but they quit that cuz of all the malware they got.) They're using XP home, and the following security apps which are exactly the same as I'm using and I'm having no problems with I.E./Yahoo or Netscape/Excite on either wireless or cable - Ad-Aware Ad-Watch AVG Free cwshredder ewido security suite Sygate personal firewall Spybot S&D Spyware Blaster Spyware Guard I suggested they open their email page, then check the internet security settings and cookie manager. Don't think that helped, haven't gotten any emails from them. Any other ideas? Thanks!
