Keith Moore (born 12 October 1960) is the author and co-author of several IETF RFCs related to the MIME and SMTP protocols for electronic mail, among others:
RFC 1870, defining a mechanism to allow SMTP clients and servers to avoid transferring messages so large that they will be rejected;
RFC 2017, defining a (rarely implemented) means to allow MIME messages to contain attachments whose actual contents are referenced by a URL;
RFC 2047 amended by RFC 2231, defining a mechanism to allow non-ASCII characters to be encoded in text portions of a message header (but not in email addresses);
RFC 3464 obsoleting RFC 1894, which together define a standard mechanism for reporting of delivery failures or successes in Internet email,
RFC 3834, standards for processes that automatically respond to electronic mail; and
RFC 8314, recommending the use of TLS for email submission and access, and the deprecation of cleartext versions of the protocols used for those purposes.[1]
He has also written or co-written RFCs on other topics, including
RFC 2964, Use of HTTP State Management (recommending constraints on the use of "cookies" to address privacy concerns);
RFC 3205, On the use of HTTP as a Substrate (discussing the use of HTTP as a layer underneath other protocols); and
RFC 3056, describing the 6to4 mechanism for tunneling IPv6 packets over an IPv4 network.
