CyberHoot Training Assignments Relay:

CyberHoot assignments are delivered through a single mail relay.  This is all you need to allow in O365 (white-list) if you are only sending training assignments, policies, or surveys to targeted email accounts.

Phishing Test Mail Relays

If you are planning on sending Phishing Tests to your clients and prospects, you will need to have them white-list all four of the Email Relays shown below either by Domain Name OR IP Address (don’t do both).

DNS Name: 

  1. relay.lockout-appie.com
  2. relay.admin-googie.support
  3. relay.server33-arnazon.com
  4. relay.admin-rnicrosoft.services
  5. relay.johnshopkinshospitals.com
  6. relay.sba-stimulus-loans.com

TIP: Copy and paste the above domains as they have many look-alike letter combinations such as an ‘i’ for an ‘L’ and an ‘r+n’ for an ‘m’.

  2. 108.52.60.139
  3. 108.52.60.140
