For complex conversions of message attachments using external,
third-party programs and site-supplied procedures, such as document
convertors, see Chapter 24. Such complex conversions can be
performed by the
Invoking the conversion channel is controlled by the
CONVERSIONS mapping table, and invoking the script channel
is controlled by the
SCRIPT mapping table. The conversion
channel or the script channel is then run to execute a site-specified
external conversion procedure.
The PMDF conversions file, discussed in Section 24.1.3, is used to specify the details of external CONVERSIONS table triggered conversions and to specify the details of some internal CHARSET-CONVERSION table triggered conversions.
If you have both a CONVERSIONS mapping table and a CHARSET-CONVERSION mapping table, the CONVERSIONS mapping table takes precedence. In this case, all entries with
