Recently bought a new 13" Macbook Pro and really like it. I have one issue however, after setting up my Charter POP email account I can't send email, only receive it. I am positive the settings and password are correct. They are the same as on my PC and iPhone 4. My household also has an older white Macbook using a Charter POP email account running Mac OS X 10.5.8 without any problems. I was reading something on the Internet where others are having this same issue and it may be due to Mac OS X 10.6.4. Some suggested changing the user name to my email address, but that didn't fix the issue for me. Any other suggestions?
