NAME
       showexternal - Fetch and display the body of a mail message that is included by reference

SYNOPSIS
       showexternal  body-file access-type name [site [directory [mode [server]]]]

DESCRIPTION
       The  showexternal  program  will  attempt to obtain the real body of a mail message that is included only by reference, using the MIME type
       "message/external-body".  It is intended to be called by metamail via a mailcap entry like the following:

       message/external-body; showexternal %s %{access-type} %{name} %{site} %{directory} %{mode} %{server} ; needsterminal

       If it succeeds in fetching the message body, showexternal will then call metamail to actually display it.

SEE ALSO
       metamail(1)

ENVIRONMENT
       The FTP environment variable can override "ftp" as the name of the ftp program.

BUGS
       Not the greatest error handling in the world.
