Will using the LocalIP range prevent relay?
The local IP address range defines which machines are allowed to send email to external address using your server. By default, the IP address range will be your C-Class address.
Using the Security>Local IP page you can define which IP addresses are ?trusted? IP addresses. You may need to increase the range to include other C-Class addresses or single, specific IP addresses.
If you need to allow users outside these ranges to use your server, see Q0173.
