I cannot send emails using WorldCast. What's wrong?
Try to send a message to yourself, so that it will be easier to detect the problem.
If you are behind a firewall or proxy, ask your network administrator how to configure WorldCast properly.
Check your server information - Your email, at the "Sender Data" tab of the tools | configuration menu, should be VALID, not BANNED. Most SMTP servers will refuse to deliver messages from invalid or banned senders, also known as SPAMMERS. In this case, try changing your sender data. THIS IS VERY IMPORTANT!
