Last Call Review of draft-ietf-eai-pop-
review-ietf-eai-pop-secdir-lc-meadows-2009-10-22-00

I have reviewed this document as part of the security directorate's

ongoing effort to review all IETF documents being processed by the IESG.

These comments were written primarily for the benefit of the security

area directors.  Document editors and WG chairs should treat these

comments just like any other last call comments.

This document extends the POP3 protocol using the POP3 Extension Mechanism

to

1) permit un-encoded UTF-8 in headers

2) add a mechanism to support login names outside ASCII character sets

3) add a mechanism to support UTF-8 protocol-level error strings in a language
appropriate for the user

The authors have done a good job of identifying the possible security
implications of this approach and have

also give references to the appropriate documents for the security implications
of using UTF-8 in general.

I don't see any further issues that need to be addressed here.
