Barracuda Spam Firewall All firmware
1) Techlib document needing update: https://techlib.barracuda.com/bsf/config365
I received notification from a Barracuda customer that Microsoft changed the process in O365 to allow a specific IP address for inbound email from BSF to O365:
From Microsoft Technician:
Currently, mail flow connectors are mainly used to enable mail flow, apply security restrictions and enable email notifications. Regarding “just specifying source IP”, you can meet your requirements by using connection filter in the Exchange admin center(EAC) by performing the steps below:
1.Login to your EAC;
2.Click protection->connection filter;
3.Double click Default, then click connection filtering.
4.Add the IP allow or block.
