MAIL TRANSFER PROTOCOL: ISI TOPS20 MTP-NIMAIL INTERFACE
INTRODUCTION
This document defines the ISI TOPS20s interface between the Mail Transfer Protocol (MTP) and the Network Independent Mail Protocol (NIMAIL) in terms of the files which implement it. The internal structure and name of each file is described below.
For a complete understanding of the MTP protocol as well as the terms used within this document, see RFC780 "Mail Transfer Protocol", RFC 784 "ISI TOPS20 Implementation", and RFC785 "ISI TOPS20 File Defintitions". The NIMAIL is documented in IEN 169, "A Simple NIFTP-Based Mail System".
And each address in the same file has the same "@host" part.
The date-time will be in the default TOPS20 ODTIM format "dd-mmm-yy hh:mm:ss" (24 hour time).
The files will named "arbitrary.NIMAIL.-1", where "arbitrary" will be somesort of date-time encoding for human uses. The NIMAIL will not care in the least what the "arbitrary" part is. These files will be placed into the NIMAIL Directory on ISIE.
DISCUSSION
The NIMAIL and MTP will each perform a transformation of the address information to create the appropriate input for the other system.
NIMAIL to MTP
The mail that arrives at NIMAIL with the information
joe%hostx%hosty%hostz@isie
will be presented to MTP with the information
FROM: <NIMAIL@ISIE> TO: <@hostz,@hosty,joe@hostx>
MTP to NIMAIL
The mail that arrives at MTP with the information
FROM: <sam@SRI-NIC> TO: <@ISIE,@hostz,@hosty,joe@hostx>
