Detecting Anonymously Registered Domains
Spamresource.com has up a piece describing a new service that could be useful in evaluating the reputation of sites you deal with — anonwhois.org returns information on domains registered anonymously. It provides a DNSBL-style service that "is not a blacklist and wasn't meant to be used for outright rejection of mail." Only 619,000 domains are listed so far, but more are added as they are queried, so the database will grow more complete. Anonwhois.org seems to be a sister site to Spam Eating Monkey.
It provides a DNSBL-style service that "is not a blacklist and wasn't meant to be used for outright rejection of mail.
Which of course means that in a year or two us mail administrators will start encountering mail servers that have been setup to reject mail based soley on them being on this blacklist.
In 2010, who *doesn't* use a "hiding" service for a domain? For fifteen years now you'd basically have to throw away any e-mail address on a domain, and get inundated with physical spam on any mailing address used.
Black listing domains because the owner doesn't want to deal with jackass spammers and bulk mailers is just stupid.
CIRA (the ".ca" registry) has a feature called "whois privacy" which hides the information of individuals who register domains by default. Only businesses get their information published in the whois database (by default - individuals and businesses can turn this on or off, although businesses need to provide CIRA with a good reason why they want their whois info hidden).
