Hello, I asked this question on openssl-users but got no response so I thought I'd take a shot on dev: I've been using OpenSSL 0.95 and 0.96 with stunnel to successfully encrypt pop3 and smtp connections from Windows NT and 98 machines running Outlook and Outlook Express. My problem is that one of the Win98 machines running Outlook is unable to connect using SSL. The error I get is this: Oct 30 08:47:42 mail stunnel[15938]: SSL_accept: error:04072073:rsa routines:RSA_padding_check_SSLv23:sslv3 rollback attack Oct 30 08:48:43 mail stunnel[15939]: 192.168.0.5.pop3 connected from 192.168.0.32:1120 Oct 30 08:48:43 mail stunnel[15939]: SSL_accept: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher Oct 30 08:48:43 mail stunnel[15940]: 192.168.0.5.pop3 connected from 192.168.0.32:1121 Oct 30 08:48:43 mail stunnel[15940]: SSL_accept: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol It doesn't appear to be a problem with OpenSSL or stunnel as none of the other client machines is having this problem. Has anyone seen this before?
