Spamhaus is a realtime blocklist, so IP addresses that have been recognised as sending out spam are listed and my mail server can refuse connections from them.
Turn off your router overnight and when you turn back on in the morning it'll most likely get a new IP address and the problem will resolve itself. If you're on BT broadband and attempting to send through an SMTP server without using a username and password, you'll also be blocked by BT and spamhaus together.
