[stunnel-users] stunnel with Winxp

i've used stunnel (v5.35) for many years, always working great. my 3rd party app running on WinXP computer was always able to send emails to gmail account. last month my app on this machine failed to send emails. changing to another (non-gmail) email account did not help. i am assuming issue is something to do with tls 1.0/1.1 on Winxp machine?

do i need to do something to get this WinXP app to be able to send emails (outgoing only) again?

thanks so much for any advice.
