RBLTracker: Custom Check Frequency, API Changes, and Twitter Support

The RBLTracker service was upgraded to version 1.12 today, which includes the following new features:

Custom Check Frequency

Customers subscribed to the Ultimate package can now adjust the frequency of their host checks, using a simple drop-down list from the Profile -> Settings section:



At the moment, customers can select from a 6 hour window, to a 48 hour window. Finer grained controls will likely be added in future releases.

API Updates

We’ve made some very basic changes to the API service:

  • Replaced all instances of the term “blocked” with “listed”. The “blocked” terminology is still available, but customers should migrate to the new terminology as soon as possible, as it will be deprecated in future releases.
  • The matched RBLs have been added to the response data. This includes the RBL matched, the RBL website, and the RBL output from DNS.
  • The API version number is now included in the response object.

An updated API document is available from the API Access section of the RBLTracker portal.

Twitter Notifications

Customers can now add their Twitter screen name to their account as notification contacts. RBLTracker will send a direct message to your Twitter account anytime a host matches (or based on your scheduling settings:



Customers must follow the @rbltracker Twitter account with the same Twitter handle in order to received direct messages. We also cannot send URLs in direct messages, due to limitations on the Twitter platform- hopefully this is something they will correct in the future.

If you have any questions or comments about any of these new features, please let us know @ info@rbltracker.com

RBLTracker: New Flexible Pay-Per-Check Pricing Model

The RBLTracker system is an automated service that scans over 60 RBL’s, 20 URIBL’s, and the Google Safe Browsing database, to see if any of your IP addresses and website URL’s are currently blocked.rbltracker

As of Sept 1st,, RBLTracker is offering a pay-per-check pricing model through its new Ultimate package. This new package lets you add as many hosts to your account as you like, and rather than paying for a certain number of hosts, you pay a low, scaled price per-check.

How does this work?

Per-Check pricing means that you can monitor an unlimited number of hosts, by simply adding credits on your account towards checks. When the credit on your account runs out, the checks stop- it’s that simple.

The cost-per-check scales with the number of hosts on your account. The current per-check pricing sheet is as follows:

  • Between 0 and 199 hosts, the cost-per-check is $0.0050/check
  • Between 200 and 499 hosts, the cost-per-check is $0.0048/check
  • Between 500 and 999 hosts, the cost-per-check is $0.0045/check
  • 1000 hosts and up, the cost-per-check is $0.0040/check

Put as much or as little credit on your account as you like- it will never expire, and we’ll let you know when your credit is running out.

How many hosts can I really add?

Really, you can add as many as you’d like! We’ve already had a customer that added over 6000 hosts to their account!

What else comes with the Ultimate package?

The Ultimate package includes all the same features of our Enterprise package, which includes multiple checks per day, SMS notifications, and much more. See the pricing page for all the package details.

RBLTracker: Automated, Real-Time Black List (RBL) Tracking

RBLTracker is a new project I’ve been working on- an automated, real-time black list (RBL) tracking service.


RBL and URIBL Monitoring

The RBLTracker system automatically scans over 60 RBLs,  and 20 URIBLs, multiple times per day, to see if any of your IP addresses or website domains are listed, giving you the peace of mind you need to focus on your business.

The list of RBLs that RBLTracker monitors will always be kept up to date with the most current list.



RBLTracker is a fully automated monitoring service, which checks your IP addresses and website domains against the most frequently used real-time black lists (RBLs) and Safe Browsing Databases.




Get alerted immediately when one of your hosts is found on an RBL, URIBL, or in a Safe Browsing database.

Your RBLTracker account can be configured with multiple email addresses and phone numbers, for receiving alerts about your hosts. Each contact can be individually configured with different notification rules, to control how each contact receives alerts when one of your hosts is blocked.


Google Safe Browsing

The Google Safe Browsing database includes lists of website domains that may be dangerous to visitors, because they are suspected of phishing or malware.

RBLTracker will check your websites against the Google Safe Browsing database, and alert you immediately if any errors are found, ensuring that your visitors can reach your websites.


API Access

RLBTracker includes a simple, read-only, REST based API, that lets you poll our database for the current status of your hosts.

The RBLTracker API can easily be integrated into existing monitoring systems, like Nagios or Zabbix, by performing a simple HTTP GET request for the list of currently blocked hosts. The response data can be returned either as simple XML, or as a JSON object.

    echo file_get_contents('https://rbltracker.com/api/blocks.json?api_token=123');

    "status_code": 200,
    "status_message": "Ok",
    "total_blocks": 1,
    "data": [
            "id": "5afd618836c251cbb066803f25b87fa1",
            "host": "",
            "name": "Primary Mail Server",
            "status": "active",
            "last_checked": "2012-12-30 21:00:07 EST",
            "first_blocked": "2012-12-17 11:05:03 EST",
            "block_period": "13 days 13:35:58",
            "blocked": "1"

Don’t let your customers be the first to know when your email systems or websites get blocked.
