One of the customers has a major networking problem that hasn't been fully analyzed yet. Sniffing his IMAPS connects on the server side, I see no (necessarily fragmented) TLSv1 Client Cert + Key Exchange happen; instead, after ~60s, we receive a single packet with "TLSv1 Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" *and* the TCP FIN+PSH+ACK flags set
ask that user to restart his network-devices
i faced it way too often in the last few years that encrypted connections where broken on customers side and after restart his crap of router all went fine again
