Each request to your Tor client (in sys-whonix) via SocksPort is accompanied by a SOCKS username and password. By clicking "New Tor Circuit for this Site" in Tor Browser, you are changing the password component, which causes the Tor client to generate a new circuit for the same first-person domain when a request is received. Thunderbird is torrified by an extension called TorBirdy. Your requested feature has been tracked for quite some time (5 years) but appears nearing implementation now that Thunderbird-related roadblocks have been cleared. (https://trac.torproject.org/projects/tor/ticket/6359) Also, the main reason for that ticket is not circuit swapping but stream isolation. At present (Whonix bonus), each different email server you connect to is given a different circuit. With #6359, multiple accounts at the same email provider can also be isolated by circuit. Currently, you can generate new circuits for all future Tor requests by using the "New Identity" feature via one of the following equivalent options: 1. From anon-whonix, use "New Identity" in Tor Browser. (applies to all Tor connections, not just the browser.) 2. From sys-whonix, use arm/nyx (monitoring tool) to send New Identity request 3. From sys-whonix, send SIGNAL NEWNYM via telnet to 127.0.0.1:9051 > More specially towards the question at hand, I think it's tricky to do > something like that in Thunderbird, but I'm not a programmer, so I wouldn't > know for sure.
