Sorry for taking such a long time, but you should have posted your followup to
the list.

In the first headers add command in the system filter. That was my plan at
least. So:

if first_delivery
then
        headers add "Old-Subject: ${sg {$rh_Subject:}{\\n([ \\t])}{\$1}}"
        headers remove "Subject"
        headers add "Subject: $rh_old-subject:"
        headers remove "Old-Subject"
endif

headers_rewrite is completely different - it rewrites addresses in From, To,
etc.
