- For Gmail, Hotmail and many others you have to select STARTTLS under Connection Type in ContaCam's Email Send Configuration dialog.
- For some free email providers it's necessary to enable POP/IMAP/SMTP access in their web interface settings page.
- If it says something like "Please log in with your web browser and then try again" then you probably tried too much. That's a security measure of free email providers, so do exactly what is says, login to the web interface and confirm that you were not hacking your own account!
