Eveytime I try to send something, I get knocked of the internet, and it keeps giving me error. I put on the outgoing mail smtp.mail.yahoo and pop.3.mail.yahoo for incoming and still error comes up.

If you want to use Outlook, Outlook Express, Thunderbird or other third party email clients to view your email you have 2 options.

Click on YPOPS link on the left.


Then Click on Configuring email clients towards the bottom.


Choose the appropriate link for your mail client.





I currently utilize version 2.0.0.4 of Thunderbird


and version 0.8.3 of YPOPS (there is a more recent version of YPOPS that you need if you are Yahoo Beta Mail) and have no problems.
