 	In Windows 7, Microsoft has commented out the localhost entries in 
the hosts file for "security" reasons due to hackers editing the hosts 
file and wrecking stuff.  They rely on an internal dns mechanism to 
provide the proper ip address for localhost.  However, today, we 
uncommented the entries and you can still redirect localhost to any ip you 
want, so I fail to see how commenting them provided any security.

 	I was in front of the computer that wasn't working, and it turns 
out he was using the cygwin telnet, which (at least the version he 
installed) doesn't support ipv6, and so that explains the problem (windows 
programs use ipv6 by default, his cygwin telnet was using ipv4).

 	It turns out that our 3rd party smtp/pop3 library that we are 
using doesn't support ipv6 anyway, and so me disabling stunnel's ipv6 
support isn't limiting anything.

 	Thanks for your help.

This problem will take an infinite amount of time.  This doesn't
seem very feasible, since we don't have an infinite amount of time.
In fact, we have less than a month.
