We are using Barracuda 300 model (Firmware v8.1.0.003 (2018-11-27) device to filter incoming emails.
We have proper SFP published for our domain. and recently enabled SPF check up in the device with soft/hard fail TAG option for SFP checkup.
We want to bypass single public IP (18.104.22.168) from SPF checkup , we added it in the BLOCK/ACCEPT > SENDER AUTHENTICATION > UNDER SFP , > EXEMPTION IP, then waited an hour, but still email from that IP is blocked on reason of Sender Spoofed
Why this option not working?
