And where are you putting this?
If you have that in bounce_matching_headers, you don't want the ^. The
syntax there is the header followed by a regexp to match. E.g.
subject: .*example
or even (I think)
subject: ^.*example
Both the header and regexp are case insensitive.
If it's in header_filter_rules
^Subject: .*Example
should work (and it too is case insensitive).

If the above doesn't explain it, it's possible the header is rfc 2047
encoded as in
Subject: =?utf-8?b?RGVzcGVyYXRlIGZvciBhIEV4YW1wbGUK?=
which decodes to
Subject: Desperate for a Example
but headers should be rfc 2047 decoded for header_filter_rules but not
for bounce_matching headers.
Also note that bounce_matching_headers is called "Legacy anti-spam
filters" for a reason.
