MIME operates as a standalone utility to interpret MIME-formatted
messages received by VMSMAIL. Use the VMSMAIL command EXTRACT/NOHEADER
to extract a MIME-formatted message received by VMSMAIL into a text
file.
MAIL> EXTRACT/NOHEADER filename
A message is opened for read access in one of the following ways:
$ MIME filename.xxx
MIME> OPEN filename.xxx
The OPEN command opens and decodes the message file, in preparation
for file viewing.
Use the MIME READ command to display the file.
MIME> READ
1 – Notes on Content-types
Not all attachments (content-type/subtypes, such as .DOC and .XLS),
can be displayed with the OpenVMS MIME utility. OpenVMS MIME
displays only the attachments that have been defined and have a
native OpenVMS viewer application installed and associated with
that defined content-type/subtype.
Example OpenVMS native viewer applications include NETSCAPE to
display .HTML and .HTM attachments, and Freeware X-VIEW application
to display image types .JPG, .GIF, and .JPEG subtypes.
Also note that foreign commands must be defined for invoking these
native viewer application images. This is so OpenVMS MIME can pass
a filename (string) representing the attachment to the viewer
application, for example:
NETSCAPE :== $ SYS$MANAGER:NETSCAPE-EXPORT-ALPHA-V303C4R-JAVA-GOLD.EXE
XV == "$ SYS$LIBRARY:XV.EXE"
Content-types/subtypes are defined internally by OpenVMS MIME and
in optional MIME$MAILCAP.DAT files.
The MIME command SHOW CONTENT lists the content types of files
that can be displayed with the READ command. Other optional types
are defined in MIME$MAILCAP.DAT file.
MIME> SHOW CONTENT_TYPE
See the READ command and SHOW CONTENT MIME$MAILCAP.DAT command for
more information and its security implications.
