Issue 10: New MailHop DNSBL: Spamhaus PBL
September 1, 2007
We have added a new DNS Black List, called Spamhaus Policy Block List (PBL). This blacklist is another tool users have to reduce spam. Taken from the Spamhaus page:
The Spamhaus PBL is a DNSBL database of end-user IP address ranges which should not be delivering unauthenticated SMTP email to any Internet mail server except those provided for specifically by an ISP for that customer’s use. The PBL helps networks enforce their Acceptable Use Policy for dynamic and non-MTA customer IP ranges.
Considering that network operators are the ones who elect to both provide ranges to block but recognizing that some ISPs may be overzealous to prevent their users from sending mail, we have categorized this blacklist as medium risk.
As with our other DNS blacklists we offer, they are added and chosen based on user input. Want to see a blacklist we do not offer? Head over to our corporate journal posting and leave a comment for us. Here is a list of our currently supported DNSBL.
