Not mapping the attribute suspected is a simple way to prevent a header from being set for it, and given a separate installation and a trace it is eminently possible to reproduce a test of the processing of a message given other manipulation of security policy to bypass checks for freshness and other factors.

Then there really isn't any doubt, nor any doubt that IIS is so broken that it apparently doesn't honor the setting you're trying to change, or has some inherent limitation that overrides the setting.

Assuming the data is all ASCII/non-unusual, then I don't think there's any real doubt, but I would be concerned about there being multi-byte UTF-8 data involved too.
