When I run spamassassin -D --lint I am noticing this message: "config: SpamAssassin failed to parse line, skipping: rewrite_subject 0 Argument "" isn't numeric in addition (+) at /usr/lib/perl5/site_perl/5.6.1/Mail/SpamAssassin/Conf/Parser.pm line 572."
Spamassasin still seems to work though. I am not sure why this error occurs or what to do about it. Steve Cohen
