SYNOPSIS
XTrackHeader = X-header-name
DESCRIPTION
The XTrackHeader slow.conf configuration item allows
a header to be inserted into each message to show that
it was already screened by slowmilt. This item
defines the name part of the header (the part to the
left of the colon).
XTrackHeader = X-slowmilt-reviewed
The default if this XTrackHeader item is omitted is to
not insert a header. If XTrackHeader defines a header
name, slowmilt will insert that header if it is
not already found, and give it a value that is the IP
number that was recorded:
X-slowmilt-reviewed: 123.45.67.89
