The IESG has approved the Internet-Draft 'On-Demand Mail Relay (ODMR)' <draft-gellens-on-demand-07.txt> as a Proposed Standard. This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person(s) are Keith Moore and Patrik Faltstrom. Technical Summary This specifies a method for fetching SMTP messages via a mechanism similar to the ETRN method, but one which works when the client which requests the mail uses a dynamic IP address. The basic functionality is that the server listens for incoming connections on a port different than SMTP. Greetings are exchanged between the server and client, after which the client authenticates using the SMTP-AUTH extensions. After that is done, the client can via the ATRN command request that the roles changes, and the server starts working over the same TCP connection as an SMTP client for the domains which the authenticated client has access to. This is not an extension to the SMTP service running on port 25, while the SMTP protocol syntax is reused for this ODMR (On-Demand-Mail-Relay) protocol on port 366 which is reserved for this service. Working Group Summary There was consensus on the mailing list about this solution to the problem. Version -06 of the protocol was last-called, and changes to -07 reflects issues brought up during the last call. Protocol Quality The spec was reviewed by Patrik Faltstrom
