I noticed that Intrusion detection is sending emails when an IP gets banned from root@hostname instead of using the From email specified under Admin > System Settings > System Misc > Notifications or Admin > System Settings > Email Settings
Thanks for reporting it. We will check it.
We have addressed this issue on VitalPBX 3.1.5 R4
Seems like this issue is back in the latest version.
Here’s a raw email that was blocked by our SMTP gateway due to it using a wrong from address.
