- Mail Analyzer
Mail Analyzer is a tool that will break apart an email and will analyze every component. Individual parts are virus scanned, received header IPs are checked against blacklists and the whole message is checked with SpamAssassin. Start using it today!
- IP to ASN mapping
The IP to ASN mapping service allows users to find info about the network being announced by performing a lookup on a single IP. We provide DNS zones and direct download of the zone files free to the public. Usage for the DNS zones can be found on the usage page or you can download the full zones.
- Geographic connection tracking and blocking
Our GeoBL service is a free public service designed to help people visualize the sources of SMTP connections. The connecting IPs are tracked based on source domain and country to help you better identify the major sources of email into your network. In addition, blocking based on geographic location (country and continent) is available for admins that want to refuse all mail from a region. See our GeoBL site to get started.
- Anonymous Whois List
AnonWhois.org is a list of domains that use an anonymous, private or proxy whois service to hide their true contact details. It was created to be a drop-in replacement for the now defunct open-whois.org. Take a look at the usage page to start using it.
- Blog Spam Blacklist
BlogSpamBL.com is a realtime blacklist of comment spammers that hit our honeypots. More information is available on the usage page.
