PMDF System Manager's Guide

The filter keyword may be used on the l (lowercase "L"), msgstore, and popstore channels to specify the location of user filter files for that channel. It takes a required URL argument describing the filter file location. For details on the URL format and the general use of this keyword, see Section 16.2.1. nofilter is the default and means that user mailbox filters are not enabled for the channel.

The sourcefilter and destinationfilter keywords may be used on general PMDF channels to specify a channel-level filter to apply to incoming and outgoing messages, respectively. These keywords take a required URL argument describing the channel filter file location. For details on the URL format and the general use of these keywords, see Section 16.2.2. nosourcefilter and nodestinationfilter are the defaults and mean that no channel mailbox filter is enabled for either direction of the channel.

The obsolete channelfilter and nochannelfilter keywords are synonyms for destinationfilter and nodestinationfilter , respectively.

The fileinto keyword, currently supported only for msgstore channels when delivering to the PMDF MessageStore, specifies how to alter an address when a mailbox filter fileinto operator is applied. For msgstore channels, the usual usage is

fileinto $U+$S@$D

meaning that the folder name should be inserted as a subaddress into the original address, replacing any originally present subaddress.
