My current .sig file. Any word on trying to get the perl parts shrunk down smaller? 
eval join"",map{chomp;s/^[^>]+>\s*//;$_}grep{/>/}<DATA>; __DATA__

The code needs to take an IP address out of a Received header (procmail will unmunge it so it's one header/line), reverse the numbers, and look up a host to check if it's on a DNS Blacklist.

One hint: The first line takes care of any bad breaking. 

eval join "",
   map {
      chomp;
      s/^[^>]+>\s*//;
      $_}
         grep{/>/} <DATA>;

So lets see now... <DATA> sucks in the rest of the .sig. Th' grep filters everything but three lines (which have ">" up front), in which the map will remove any end-of-line characters, strip off everything up to and including "> ", and the join will just merge everything into one line which eval gets to run through.
