Email receiving rejection based on IP address or block of addresses

This is what I wrote to Dream Host support, and told me to post it here.

Hello nice people at DreamHost.

After browsing my spams, the spam mails are mostly coming from a couple of range of IP addresses.

I’d like you to add a feature to not receive any mails from specified IP addresses or ranges of addresses.
That would cut down good chunk of my spams.

A better feature is to parse the mail header and figure out the actual origin, but I would not ask that much for now.
