IMPORTANT: CHANGES TO BULLPHISH ID SENDING DOMAINS EFFECTIVE OCT. 21

Attention BullPhish ID customers, 

Earlier this year, Microsoft announced that it was changing the behavior of override functions in Exchange Transport Rules (ETR) with respect to high-confidence spam/phishing, including those from 3rd party phishing simulation campaigns. 

As part of their Secure by Default push, ETRs no longer honor the bypass spam filtering option for high-confidence spam/phishing.

The replacement capability is called Advanced Delivery and is now available to tenants for configuration, but it limits the list of allowed phishing simulation domains to 20. (Initially, Microsoft limited the number of allowed domains to 10 but increased it to 20 as of last week).  

BullPhish ID has had 19 sending domains available for the phishing simulation campaigns. However, based on our partners’ feedback, we are reducing our list of sending domains to nine effective October 21, because several of the 19 domains are either similar to an existing domain, could be replaced by an existing domain, or are invalid. 

Here are the sending domains that will remain(highlighted in GREEN below):

We have removed the domains ON THE LEFT(highlighted in YELLOW). The removed domains have been replaced by the approved domains ON THE RIGHT(highlighted in GREEN), as follows:
