Make Thunderbird work with CCProxy
1. On the CCProxy, options make sure that you have checked the SOCKS check box and have set the port for it (figure 1).
2. Now, in the Mozilla Thunderbird, open Options, then open connection window from "Advanced > Network & Disk Space" tab and set the settings as below (Figure 2).
Notes: You need to make sure that "No Proxy for" input box is empty.
3. Now, try connect thunderbird with some email client and it will work (Figure 3).
