Plesk Mail Whitelist: 127.0.0.1 /8 or 127.0.0.1 /32

Plesk Users,

We received an attack from 127.0.1.50 (spam). We assume that the attack came from webmail. I have heard that 127.0.0.1 /8 makes the server an open relay. Is this true? Should we be using 127.0.0.1 /32? If we change it to /32 what would that effect?

Why does Plesk by default use 127.0.0.1 /8?
