A bogus SSL server certificate has been installed to:
$HOMEBREW_PREFIX/etc/stunnel/stunnel.pem
This certificate will be used by default unless a config file says otherwise!
Stunnel will refuse to load the sample configuration file if left unedited.
In your stunnel configuration, specify a SSL certificate with
the "cert =" option for each service.
To use Stunnel with Homebrew services, make sure to set "foreground = yes" in
your Stunnel configuration.
