What are my PMDF filtering options?
PMDF filtering can occur on three levels. 1. System Level Filters System level filters are exactly as the name implies. All mail that comes into the system is run through this filter. The system level filter is applied whenever a message gets enqueued to a channel. If a message is enqueued a number of times (once, say, on tcp_local and once on conversion and then the l or msgstore channel), then the filter is processed each time. This does not cause a problem since messages can be enqueued to different channels and the amount of overhead to do this operation is minimal. Some channels, such as the conversion channel, may change the content of a message, so it can be advantageous to run through the system filter another time. To activate the system level filters, simply create a file called PMDF_TABLE:PMDF.FILTER or /pmdf/table/pmdf.filter (UNIX)or C:\ pmdf\ table\ pmdf.filter (Windows NT). This can be done via the PMDF Web-based interface or by using a text editor. The system level filt
