Why not integrate a whois date lookup directly into SURBL or URIBL?
Design an encoding system whereby
suspectedspammydomain.spammertld.dr.surbl.org (or uribl.com) would
return the date somehow regex encoded in the IP address.  Then write a
nice SA rule that decodes it, also using regex.  Are there any regex
geniuses out there that could encode a date in an IP address?
