1.2.3.4 is the address you're listening on.

How do you define "incoming"? I thought your wanted different content
filters for mail from your users and mail coming from the outside. In
that case, you need one IP address for each class of users and content
filter. You can also use the FILTER access map action, in which case
you don't need more than one IP address to listen to.

You've misunderstood what the IP addresses mean.
