Ooh, isn't this going to generate a number of false positives? Should we
not match on the start of the line? Can we say this?:
if $message_headers matches "^xxxx: "
If xxxx is pretty unique, the false positive risk is low.
True, but the false positives might be very important. For example, if xxxx
is X-spam this subject might cause a message to be /dev/nulled:
Subject: What's that "X-spam:" header about, then?
You would have
to say "(?m)^xxxx:" to enable "multiline mode" if you want to be
pedantic. Or use "\\N(^|\\n)xxxx:".
