To ensure the effective delivery of our simulated phishing emails, you may need to whitelist our servers, we recommend whitelisting by hostname which is covered in this article.
If you need to whitelist by Email Headers instead, see the following articles:
- Whitelist by Email Headers in Excahnge 2013, 2016, or Office 365
- Whitelist by Email Headers in Exchange 2010
Whitelisting by Hostname in Exchange 2013, 2016 or Office 365
