Anyone know why I can't send emails using my normal Mac Book Mail program in certain countries? I use a POP email server from the states and have to go to its webmail version to send, but I can receive just fine. This has been happening in Shanghai, Almaty, Taipei, Narita, and a host of other countries. In about half of the countries the email works fine both ways. Other friends have the same issues too with their mail.

Is there a preference setting that I need to be changing or am I SOL?

Thanks,
