Hi there. I live in a country undergoing a coup and human rights abuses occurring daily. In order to send messages with a minimum chance of identification I set up a webmail account, this does not seem to provide useful IP information in a test email but presumably ones ISP could log your use of the webmail and conceivably intercept text transmitted. Is this so and if so what alternatives does one have, can you use a service such as anonymouse.org or could this still be vulnerable at the ISP?

Unless you have a static IP address, it is highly unlikely that the email could be traced back to you. Nevertheless, since everyone must have an ISP, any ISP can feasibly monitor traffic going through it's site - even to anonymouse.org. Since you are obviously not in the United States, I'm not aware of the technology available to you or the laws and rights in your country. Probably your best bet is not necessarily to send the messages anonymously, but to encrypt them so that even if the messages are monitored, they can't be tagged as subversive because there's no identifiable text.
