In this page: http://freebsd.qmailrocks.org/clamspam.htm
The instruction is add:
rewrite_subject 1
required_hits 5
However, "rewrite_subject 1" is not recognise when i do spamassassin -D
--lint
This is the error:
[2276] warn: config: failed to parse line, skipping: rewrite_subject
Which version of spamassassin did you install? Do you know?
Did you read any of the information that came with the SA release, or just
that page you reference?
Neither required_hits nor rewrite_header is going to work on any modern
version of SA.
I suggest you uninstall, find a version of spamassassin 2.64 or earlier, and
install it. Then your config file will work.
