WebCam Monitor will work with any Internet Service Provider that supplies an outgoing mail server using the standard SMTP protocol.
The WebCam Monitor User Guide has a section on configuring outgoing mail.
You will have to consult your Internet Service Provider to get specific information such as the name of their SMTP server, and whether login and password are required.
GMail requires encryption to use their servers for outgoing mail. We plan to support encryption and GMail in a future release of WebCam Monitor.
