Somebody using your IP address [80.89.179.128] appears to have been
sending Advanced Fee Fraud emails, and thus the IP address got listed in
the Spamhaus Block List.

You should get your ISP to talk to Spamhaus, tell them what they did to
prevent this from happening, and ask them to remove the listing.
