I just installed 10.1 toady and was trying to set up my e-mail accounts. The problems I'm running into are: I can't send mail out using any of my accouts, (Yahoo, Hotmail, and another more private account). I can receive e-mail, except from Hotmail. But when I send mail out, it says it cannot determint the IP address of host. I'm using the same info I used in Entourage 2001. Is there a difference?
