CyberHoot’s Email-Relay IP Addresses, Domains, and Allow-list Articles:

This article is a reference to CyberHoot’s mail relay IP Addresses and Domain names.  The process of allowing phishing tests through to your end users inboxes is dependent upon your mail and spam filters.  CyberHoot provides instructions and scripts on bypassing Microsofts Spam, Clutter, and Junk filters as well as adding our mail domains to the safe senders lists.  

Please note that if you are using multiple filters in series, you will also need to set up X-Headers in addition to allow lists to deliver email to your end users.  You may wish to run powershell scripts we have prepared to make your life easier.
