Okay, so it's not running; but has it logged any error messages using
the system's syslog?  Is there anything stunnel-related in, say,
/var/log/messages, /var/log/syslog, /var/log/daemon.log or anything

To keep stunnel's messages into a separate file, you might also add
output = /var/log/stunnel.log
and then you'll know for sure if it logs anything.  Of course, it
will need permission to write to that file - it seems to me that you
might be trying to run stunnel as a non-root user, nothing wrong with
that, but then it might not be able to read its certificates and stuff.

For debugging purposes, try something like:

debug = debug
foreground = yes

For normal use, try this instead:

debug = debug
output = /home/your-username/stunnel.log

This section looks fine.  Now the most probable cause - IF you are
running stunnel as a non-root user - would be that it is looking for
its certificates in, say, /etc/stunnel.conf or something, and you do
not have permission to read that file.

No matter if you are running it as root or not, try running it with
foreground = yes so it does not daemonize and it sends all its output
to the standard error stream where you can see it.
