[stunnel-users] blackhole problem - please help to tune stunnel

Dear stunnel users,

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?
