Blocklist filter based on IP address

I seem to get a huge amount of spam from “random source” and “random return” addresses, however if you look at the message source you find that they’re all from a small group of spam servers. I, and I hope others would find it very useful if you could create a rule based on the sender’s IP address and therefore block thousands of spams with a very few rules.

Would anyone else find this useful?

Cheers

I think in most cases this would not be necessary since SpamSieve automatically learns from the IP addresses. However, if you want you can create rules like that by matching against the Received header.
