Hi, I have always used mac mail with no problems, setup hotmail and i was able to send and receive all my emails. I have now sold my macbook pro and am just using a macbook but have backed up the macbook pro and installed it onto this macbook. Since doing this i am unable to send emails using macmail but can receive them. I have been into the settings and cant find what is wrong. I am using the latest version of OSX - 10.8.3 Can anyone help? ---------- Gmail works fine btw!
