please advise how to solve the following:

- an Application connects to stunnel-client (installed at the same machine);

- stunnel-client tries to connect to stunnel-server (remote), fails and sends RST to the App;

- but the App has already sent some datagrams to stunnel-client during TIMEOUTconnect period and they aren't transferred to stunnel-server.

Is there any way to make stunnel-client delay its ACK to the App until the connection to stunnel-server is established?

Thanks!
