It is enabled by default, but only applies to messages delivered after
you started to run 2.2.1 or later (unless you reconstruct).

Only a subset of X-Whatever headers are cached, but just about everything 
else is cached apart from the Received headers.

I should point out that the code in Cyrus is a significant improvement on 
my original version, courtesy of Rob Siemborski. The version in Cyrus 
makes it easy to add headers to the list which is cached.
