MAIL TRANSFER PROTOCOL: ISI TOPS20 MTP-NIMAIL INTERFACE
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 RFC 780 "Mail Transfer Protocol", RFC 784 "ISI TOPS20 Implementation", and RFC 785 "ISI TOPS20 File Defintitions". The NIMAIL is documented in IEN 169, "A Simple NIFTP-Based Mail System".
1. NIMAIL to MTP
NIMAIL will present mail for processing by MTP using the files specified in RFC 785.
2. MTP to NIMAIL
MTP will present mail for processing by NIMAIL in files of the following form:
address <CR><LF> address <CR><LF> address <CR><LF> <CR><LF> Via: USC-ISIE; date-time <CR><LF> header . . . <CR><LF> body . . .
Where each address is of the form:
Sluizer & Postel Page 
July 1981 RFC 786 ISI TOPS20 MTP-NIMAIL Interface
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.
The NIMAIL and MTP will each perform...
