Hello, stunnel currently does not send a list of accepted CAs, see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=327001#c20 . Sending the list was #if 0-ed out sometime between stunnel 3.22 and 4.00, with no change log entry AFAICS. Does anyone remember know why was it disabled, and whether it is safe to reenable (e. g. using the attached patch)? Thanks, Mirek
