You could set up a gmail account via tor. Then point a stunnel at

you have a copy of their public cert first and that the stunnel

play at one point. I had to make sure Exim stripped the Received headers
and sent a suitably anonymous EHLO when talking to their service but
otherwise it worked.
It's hard to tell if your SMTP client or stunnel itself send
identifying information. :(
I initially set Exim to freeze the messages in the queue so I could
inspect their headers and body, to check for just this. You can then
flush an individual message using "exim -v -M message_id" allowing you
to watch all communication going back and forth between the two servers.
I never considered that stunnel might send identifying information of
some sort though. Hmmm. Does anyone have any experience of using stunnel
with tsocks over the Tor network?
