Hello NANOG, Belated new year wishes.

I would like to gather some feedback from you all.

I'm trying to propose two things to the Internet Standard and it's related to SMTP.

(1) STARTTLS downgrade protection in a dead simple way

(2) SMTPS (Implicit TLS) on a new port (26). This is totally optional.

I posted my proposal in IETF mailing list. I got very good feedback there. Some support my proposal. Many are against it.

What is the IETF draft name? Which IETF mailing list did this discussion happen on? -- Doug Royer - (http://DougRoyer.US http://goo.gl/yrxJTu ) DouglasRoyer@gmail.com 714-989-6135
