Blocking IPs on Mail Servers

Starting with H-Sphere 2.4.2 and higher, you can block specific IPs from sending you mail. The incoming messages from this IP will bounce back to the sender.

To deny relay to specific IP:

1. Select Mail Servers in the E.Manager menu.



2. At the bottom of the page choose mail server from the drop-down box.
3. Choose Deny relay and enter necessary IP.
4. Enter note, if necessary, and click the Add button.
The blocked IP will appear in the Mail Server Relays section



You can remove the blocked IP from the list at any moment by clicking the Trash icon on the right.
