It means that you are going to have to use Stunnel as an intermediary 
between Turnpike and the mail server, as TP doesn't include built-in 
support for TLS or SSL. In recent years, the official Stunnel site has 
only provided a 64-bit version of Stunnel. but you can download a 32-bit 
version from here:

https://github.com/josealf/stunnel-win32

The most up-to-date version seems to be 5.77.

As I no longer use TP myself - having gone over to a 64-bit PC, I'm 
afraid I can no longer remember enough to provide much help with how to 
configure Stunnel and TP to work together, but hopefully someone can 
step in to assist. Failing that, although Googlegroups is no longer 
operating, its archived posts are still searchable on the web.
