We are moving to a new SMTP server, “34.237.252.20” to improve the phishing simulation email deliverability. We are currently in the migration phase, and the new SMTP server will be LIVE in January 2022. Your campaign email deliverability can be affected if the new SMTP server is not whitelisted.  We strongly recommend whitelisting the new server IP address no later than January 20, 2022.

For reference, we’ve updated the following BullPhish ID guides with the new SMTP server IP address:

• Microsoft Office 365 Whitelisting Guide
• Reference Guide for Deliverability
• Google Admin Whitelisting Guide
