SMTPs SSL/TLS secure?
I was wondering if someone could help me verify the security of smtps. I have configured Postfix (with ispconfig2) to use pop3s, Imaps and smtps port 645. The maillog shows they are all using TLS and thunderbird picks up the cert for (server.com:465). When I use wireshark however smtps is using TCP not TLS. Is there something beyond my understanding going on? STARTTLS maybe?
