1. Introduction
This document describes methods for carrying PostScript information
in the two standard mail systems MIME and X.400, and the conversion
between them. It uses the notational conventions of [BODYMAP], and
the conversion is further described in [MIXER].
Two ways of carrying PostScript in X.400 are described. One is using
the FTAM Body Part, and one uses the Extended Body Part originally
described in RFC 1494.
The FTAM method is recommended.

2. The PostScript body part
Carrying PostScript in X.400 as an Extended Body Part was originally
defined in RFC 1494. This specification carries that work forward
now that RFC 1494 is obsoleted by [BODYMAP].
The following Extended Body Part is defined for PostScript data
streams. It has no parameters.
postscript-body-part EXTENDED-BODY-PART-TYPE
DATA OCTET STRING
::= mime-postscript-body
mime-postscript-body OBJECT IDENTIFIER ::=
{ mixer-bp-data 2 }
3. The PostScript FTBP
The PostScript FTBP is identified by having the
FileTransferParameters.environment.application-reference set to id-
mime-ftbp-postscript.
The definition is:
id-mime-ftbp-postscript OBJECT IDENTIFIER ::=
{ mixer-bp-data 6 }
4. The Application/PostScript content-type
In MIME, PostScript is carried in the body part
"application/PostScript", which is defined in RFC 1521.
5. MIXER conversion
X.400 Body Part: Extended Body Part, OID mime-postscript-body MIME
Content-Type: application/postscript Conversion Type: No conversion
The two representations of PostScript both contain a single stream of
octets. This stream of octets can be copied with no problems between
the representations. No other data needs to be converted.
6. MIXER conversion
X.400 Body Part: FTBP, OID mime-ftbp-postscript-body MIME Content-
Type: application/postscript Conversion Type: No conversion
Alvestrand Standards Track [Page 2]
RFC 2160 Carrying PostScript in X.400 and MIME January 1998
The two representations of PostScript both contain a single stream of
octets. This stream of octets can be copied with no problems between
the representations. No other data needs to be converted.
7. OID Assignments
The first OID is also defined in [BODYMAP].
POSTSCRIPT-MAPPINGS DEFINITIONS ::= BEGIN
EXPORTS -- everything --;
IMPORTS
mixer-bp-data
FROM MIXER-MAPPINGS
id-mime-postscript-body OBJECT IDENTIFIER ::=
{ mixer-bp-data 2 };
id-mime-ftbp-postscript OBJECT IDENTIFIER ::=
{ mixer-bp-data 6 };
END
8. Security Issues
The issues concerning PostScript and security are well discussed in
RFC 2046. No additional security issues are identified by this memo.
9. Trademark Issues
PostScript is a trademark of Adobe Systems, Inc.
