For an up-to-date list of BullPhish IP addresses, see our "Reference Guide for Deliverability" document.

  3. Enter the IP address(es) and Subnet Mask(s). You can find the most up-to-date list of our IP addresses under the Guides & FAQ > Reference Guide for Deliverability

Barracuda Sentinel Allow Senders

Barracuda Sentinel's Allow Senders list allows BullPhish ID emails to bypass your organization's current whitelisting rules. See Barracuda's How to Allow Sender article for more information.
