Aha. That explains it. Thanks. Would've been nice with a flag to
match the entire header, then .. wink wink nudge nudge .. ;-)

Sorry I didn't say so; both the test messages was delivered over
SMTP from another host, and made it into the spool without any rewriting
taking place - it happens as the message is delivered. So neither of
these really explains why the rewriting happens, even before taking into
the account that it happens only if headers_rewrite is set in the
transport, which makes it even more of a mystery to me.
