New description:

 TorBirdy should not use the same circuit that any other torified
 applications may use. Streams should get isolated.

 A different circuit should also be used for each account, similar to what
 Tor Browser does when isolating different domains.

Comment:

 Tor Browser now uses SOCKS username/password to use different circuits for
 each domain. Does Thunderbird now support using SOCKS username password as
 well? Would it be complicated to get a different circuit for each account
 now that it's a reality?

 One corner case to be aware of is POP before SMTP. I don't know if these
 kind of setups are still in use, but they were popular at some point. It
 would probably be best if the same circuit can be used in such a case, as
 I believe some implementation would ensure that the same IP is in use for
 both POP and subsequent SMTP. This is still a minor use case and should
 not block getting proper isolation between accounts.

 Thanks!
