Today, many email client > and server supports TLS Not my favourite old MUA, unfortunately. When I implement a simple script I'm limited to a socket interface, and in that case cram-md5 / digest-md5 / otp is the best I have. And the server in question offers login / plain / cram-md5 for AUTH. > I think the best option for this protocol, given issues > raised by Simon regarding DIGEST-MD5, is TLS+PLAIN. Where that's possible it's fine. I'm more interested in the case where it's impossible. My understading of the draft is: "Whatever you do stay away from PLAIN (or the obsolete LOGIN) without TLS, use at least CRAM-MD5". Maybe Brian's proposed compromise covers this concept somehow. And he wanted "known weaknesses [citations]". That's about today, not about some results of the not yet existing HASH WG in 2006 or later.
