PMDF System Manager's Guide

The routelocal channel keyword causes PMDF, when rewriting an address to the channel, to attempt to "short circuit" any explicit routing in the address. Explicitly routed addresses (using !, %, or @ characters) will be simplified.

Use of this keyword on "internal" channels, such as internal TCP/IP channels, can allow simpler configuration of SMTP relay blocking.

Note that this keyword should not be used on channels that may require explicit % or other routing, such as PMDF-LAN or PMDF-MR channels.
