Read NANOG archives - Verisign now allows immediate (well, within about 10 minutes) updates of .com/.net zones (also same for .biz) while whois data is still updated once or twice a day. That means if spammer registers new domain he'll be able to use it immediatly and it'll not yet show up in whois (and so not be immediatly identifiable to spam reporting tools) - and spammers are in fact using this "feature" more and more!
This tempts me to hack something into Exim that does a whois on previously-unseen sender domains, and give a deferral if the whois denies existence of the domain. Is this likely to have any meaningful effect? -- Just last week, someone called every morning to speak to President Gore. By Friday, the operator was flustered, and finally snapped, "You call every day asking that, and every day I tell you that Mr. Gore lost the election. Why?" "I just like hearing that. It's a great start for the day!"
