      Threat level/ delivery impact

      Brand/ Network Resource/ Deliverability Harm - If your firm is impacted by threats shown below, you need to take immediate action as a laundry list of negative outcomes have potentially already begun ranging from significant deliverability issues to service termination from your ESP or ISP. If ignored, your brand reputation could be permanently tarnished and easily become associated in some circles with known spam organizations such as SpamHaus’s ROKSO or other similar blacklists.

      Network Resource/ Deliverability Impact - Below are threats that could cause some significant delivery and reputational issues. At worst, you will experience continued delivery impacts and may be forced to purchase new sending domain and IP resources in order to achieve optimal deliverability.

      Impacted Delivery - The following threats will result in temporal delivery issues, diminishing your campaign's outreach and effectiveness. Prolonged sending of these threats may result in longer lasting temporary blocks leading to eventual permanent blocking of your emails. There is minimal overall brand and sending resource reputational harm from these items

      Nomination

      Automatic (upon receipt of a spam to a spamtrap mailbox), with extensive whitelists and filtering to prevent false positives.

      Listing lifetime

      Typically Permanent. Very hard to get removed.

      Notes

      ABUSE - spam and other abuse sites.

      This list contains mainly general spam sites (pills, dating, etc). It combines data from the formerly separate JP, WS, SC and AB lists.

      jwSpamSpy + Prolocation sites

      Joe Wein's jwSpamSpy program along with systems operated by Raymond Dijkxhoorn and his colleagues at Prolocation provide JP data. The resulting list has a very good detection rate and a very low false positive rate.

      sa-blacklist web sites

      WS started off with records from Bill Stearns' SpamAssassin ruleset sa-blacklist but nowadays holds data from many different data sources.

      SpamCop web sites.

      SC contains message-body web sites processed from SpamCop URI reports, also known as ""spamvertised"" web sites. The reports are not used directly, but are subject to extensive processing. Entries in SC expire automatically several days after the SpamCop reports decrease.

      Note that this list is not the same as bl.spamcop.net, which is a list of mail sender IP addresses.

      AbuseButler web sites.

      AbuseButler is kindly providing its Spamvertised Sites which have been most often reported over the past 7 days. The philosophy and data processing methods are similar to the SC data, and the results are similar, but not identical. Data sources for AbuseButler include SpamCop and native AbuseButler reporting.

      PH - Phishing sites.

      Phishing data from multiple sources is included in the PH Phishing data source. Phishing data was first provided by MailSecurity, later joined by PhishTank data, OITC phishing data, PhishLabs data and several other sources.

      MW - Malware sites.

      This list contains data from multiple sources that cover sites hosting malware. This includes OITC, The DNS blackhole malicious site data from malwaredomains.com and Malware Domain List. Some cracked hosts are also included in MW since many cracked sites also have malware. Note that the above is only a sampling of many different malware data sources in MW.

      CR - Cracked sites.

      This list contains data from multiple sources that cover cracked sites. Criminals steal credentials or abuse vulnerabilities in CMS such as Wordpress or Joomla to break into websites and add malicious content. Often cracked pages will redirect to spam sites or to other cracked sites. Cracked sites usually still contain the original legitimate content and may still be mentioned in legitimate emails, besides the malicious pages referenced in spam.
