I'm running SpamAssassin in the data ACL. I have the following in my
ACLS that adds a modified subject header:

 warn  message = X-Local-NewSubject: [spam $spam_score] $h_Subject:
        condition = ${if >{$spam_score_int}{50}{1}{0}}

And then in the system filter I replace the original header with the new one:

if $h_X-Local-NewSubject: is not "" then
        headers add "X-Local-OldSubject: $h_Subject"
        headers remove "Subject"
        headers add "Subject: $h_X-Local-NewSubject"
        headers remove "X-Local-NewSubject"
endif
