Both not quite right. You set up the sbcglobal account the same way to set up a new yahoo account. Setttings->Mail->Add Account->Y! Mail.
On the email field, just type your full address, like
RHJS@sbcglobal.net. The "@yahoo.com" will be pushed to the right and eventually disappears when you save it.
That is how I got push email and all that with the sbcglobal account. And I did not discover this. Someone else on this forum posted this, just can't find the post right now.
