Have you ever face problem trying to send out an exe file, either using email (Gmail, Yahoo Mail) or chat program (Google Talk, MSN Live Messenger)? Most of the email provider like Gmail, prevent the user to send out exe file, even if you zip the exe file.
The “RED” message pop out after I click the Send button. “WebcamViewer V1.0.zip contains an executable file. For security reasons, Gmail does not allow you to send this type of file. Your message has been moved back to Drafts.”
