Conversion Channel

The conversion channel is a very general purpose interface where you can invoke a script or another program to perform arbitrary body part processing of an email message. The conversion program hands off each MIME body part (not the entire message) to the program or script and can replace the body part with the output of the program or script. Conversion channels can be used to convert one file format to another (for example, text to PostScript), to convert one language to another, perform content filtering for company sensitive information, scan for viruses and replace them with something else.
