Gurbani Review Date: Feb-25-2014 IETF LC End Date: Mar-05-2014 IESG Telechat date: Unknown I must say that this draft was written with implementors in mind. This is very refreshing. Major: 0 Minor: 0 Nits: 4 This document is ready as a Proposed Standard. Some minor nits follow: Nits: - S2.2, "Organizational policy and good security practice often require that messages be reviewed before they are released to external recipients." Here, I suspect that organizational policy may require such a vetting but I would think that "good security practice" would not. After all, unless a party is forced to do so (the "organizational policy" part), why would one party willingly subject its private communications to a third party before sending it to the recipient? I would not consider that a third party reading my messages a "good security practice". Therefore, I would take the "good security practice" phrase out, unless of course, there is some context to that phrase that I am not privy to. - S3.3, first sentence: "A 'domain signature' is a signature generated on behalf of a set of users in the domain the users are a member of." This sentence appears rather, for the lack of a better word, clunky. How about rewriting this as: "A 'domain signature' is a signature generated on behalf of a set of users who belong to the specific domain." - S5, steps 3-A and 3-B: s/found then/found, then/ There are some more occurences of this, if you feel like it, you may want to change these to have a comma as well. - S7, first paragraph: s/permits masquerade./permits masquerading./ or, s/permits masquerade attacks./ Thanks, - vijay -- Vijay K.
