I believe (and anyone can correct me) that you should not allow your TLS/SSL to run low security handshakes or connections. This might expose your certificate. (due to low encryption) We do not allow anything lower than TLSv1 for TLS sessions. We get the "Error" in our logs to but we see these as a "Warning/Notice" ourselfs. The sender have to retort to plain text rather than we expose our certificate to malice. I see this a lot from Asian and African "senders/clients" and probably a couple of botnets trying this. No newer client should refuse using TLSv1 or higher. My guess is it's some kind of "fishing" to make you lower your security. We don't!
