This chapter describes how to use the
disclaimer channels to modify
messages as they pass through PMDF.
conversion channel allows processing of message
attachments and other body parts using external, third-party programs
and site-supplied procedures, such as virus scanners. The execution of
such procedures is controlled by the
table and the
conversions file. The conversion channel is
discussed in Section 24.1.
The PMDF conversions file, discussed in Section 24.1.3, is used to specify the details of conversion channel processing and to specify the details of some internal CHARSET-CONVERSION table triggered conversions (see Chapter 6).
If you use both a CONVERSIONS mapping table to invoke the conversion channel and a CHARSET-CONVERSION mapping table to perform character set conversions (see Chapter 6), the CONVERSIONS mapping table takes precedence. In this case, all entries with
script channel allows processing of messages in their
entirety using external, third-party programs and site-supplied
procedures. The execution of such procedures is controlled by the
SCRIPT mapping table. The script channel is discussed in
disclaimer channel allows arbitrary text (usually in
the form of a disclaimer) to be added to messages. The addition of such
text is controlled by the
DISCLAIMER mapping table. The
disclaimer channel is discussed in Section 24.3.
