Release Notes: The screen for message IDs was changed, though it still requires FQD. Message IDs must adhere to RFC 850. The requirement for at least one "." in FQD was removed due to excessive false positives. The HTML-stripping sed command was changed to be less case sensitive. Two known spammer addresses were added. '**' was added to the list of subjects that are likely spam. "unknown" was added to the list of To: addresses probably from spammers. The check for "Undisclosed Recipients" was changed to check both in the To: and Cc: lines. A check for five consecutive spaces in the subject line was added to the list of checks for common spam subjects. A line to check for '<<' or '>>' in subjects was added. The "ugly address" check was refined. The default for CHECKUNKNOWN was changed to false, since it was generating too many false positives. The check for empty Subject lines was removed, since it was generating too many false positives.
