ESMTP STARTTLS on Port 25. > My ISP's current secure email connection information is at: > > http://www.internode.on.net/support/email/secure/index.php They seem to provide you sub-standard service. Try educating them. I suspect that there is a number of mail clients that cannot do smtp-over-tls on tcp/465 in the first place. > (FYI, I'm one of the people that doesn't believe the "telnet is > insecure, ssh is safe" mantra that others keep stating, having run > secure-only telnet servers and read of man-in-the-middle attacks on ssh). When people say "telnet is insecure", they are usually referring to unencrypted telnet. Personally, I have never run telnet over TSL, but I suspect that ssh is more widely used because of its vastly superior feature set. mitm attacks are usually caused by people clicking away the "new host key" warning, but it's the same with classical TLS as well.
