I think you're going to kick yourself. ".*" ,means zero or more characters, so matches anything. It looks like the superfluous "*" is the only thing wrong here. > What is a negative match, anyway? AFAIK it just means that the rule matched without matching any actual text for the debug to display. > Am I seeing https://bz.apache.org/SpamAssassin/show_bug.cgi?id=6360 > in this case? This looks to be a bug where "negative match" is also displayed if the matched text is "0", i.e. the number zero rather than a null string.
