[stunnel-users] error:1408F10B

I'm having similar issues recently on two separate machines that are producing similar errors. In both instances, /var/log/messages starts filling up with lines similar to the following:

SSL_accept: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number

I can give further details on both systems, as well as the exact issue, if warranted. First off, can anyone explain what a 1408F10B error is? My gut feeling is that in both instances something changed on the client end (in both instances the client is a version of outlook).

Any help would be greatly appreciated.
