Why use DNS Blacklists?
"The rise of spam and other anti-social behavior on the Internet has led to the creation of shared blacklists and whitelists of IP addresses or domains. The DNS has become the de-facto standard method of distributing these blacklists and whitelists."
How do DNS Blacklists Work?
"A Domain Name System-based Blackhole List, Domain Name System Blacklist (DNSBL) or Real-time Blackhole List (RBL) is a service where with a simple DNS query mail servers can check whether a sending IP address is on a blacklist of IP addresses reputed to send email spam. Most mail server software can be configured to check one or more of such lists - typically rejecting or flagging messages if it is from a listed site."
How does Corner Bowl Email Blacklist Monitor do it?
Email Blacklist Monitoring is available as a sub-component of both Corner Bowl Event Log Manager 2021 and Corner Bowl Server Manage 2018. When you purchase either an Internet Server Monitor license or a Server Manager license simply register your license in either our latest monitoring software, Event Log Manager or our tried and true Server Manager software.
Once registered, Corner Bowl Software enables you to schedule Email Blacklist monitoring. DNS Blacklists are scanned for the existence of results such as 127.0.0.2 indicating the email server is blacklisted. If an email server is blacklisted, Corner Bowl Software sends regular email notifications to the responsible IT administrators until the email server is no longer blacklisted.
- Runs on a Windows Server or Workstation as a Windows Service.
- Includes 30+ pre-configured email blacklists
- Scans Email Blacklists at the frequency you define.
- Receive email and SMS notifications as soon as your email server is blacklisted.
- Once your email server is blacklisted, Corner Bowl includes the option to ramp up the scanning frequency so you are notified the instant your email server is no longer blacklisted.
- Includes historical and email blacklist statistics over time.

Windows Management Instrumentation (client and server)
Many functions within Internet Server Monitor utilize Microsoft's Windows Management Instrumentation (WMI) API (e.g. Event Log management, CPU and memory monitoring). This software includes options to optimize WMI packet size and performance.
Internet Server Monitor is sold in node packs. Each unique IP address or hostname that is monitored, scanned or managed by the software is a node.
Internet Server Monitor can be installed on a single host or up to as many hosts as nodes purchased.
For example, a 100 node license would enable an IT professional to install the software on 3 servers with one installation monitoring 50 servers and the other two installations monitoring 25 workstations each for a total of 100 nodes.
After you purchase a license, you have the option through this website or your reseller to upgrade your existing license with more nodes.
Once you have purchased a license, a license key will be emailed to you. If you purchase through a reseller, a claim link will be emailed to you enabling you to retrieve your key from this website. Once you have your key you will register online through the software's management console. If you are installing this software on an Air-Gapped network, you will generate license key files through this website where you will also find detailed instructions on how to apply your Air-Gapped key files.
