Add the following IP addresses and domain names to any network filters and/or domain Whitelists at your site.

IP Address Range: 216.68.85.112-115 (216.68.85.112/30 or 216.68.85.112/255.255.255.252)
Domain Names: CheckTLS.com and *.CheckTLS.com

Adding our IP address range to any network filters makes sure our tests are able to do the testing you request from our site.Our tests are non-invasive, non-intrusive, and non-obtrusive. They require no changes to your or any other system. They cause no extra processing and should not trip any security alarms.

Adding our domain to any Whitelists also makes sure our tests can do the testing you request, and it also makes sure any results we email to you get through to you and don't end up in a junk folder or thrown away.

Tue, 30 May 2017 What is the difference between Professional and Corporate Level Subscriptions?

Corporate is everything in Professional plus the ability to store batches (lists) of addresses and test them automatically on a schedule.

Professional is access to the raw tools, Corporate makes them easy to use over and over.

Professional tests things one time, Corporate is "set it and forget it" continuous monitoring of one or more email systems.

You can achieve HIPAA Compliance with Corporate. See email compliance

Corporate also has Internet Packet Sniffer and Protocol Analyzer -- very powerful tools that take some time to learn and setup.
