<div>I agree with Suresh on Spamhaus being one of the more focused and well-operated DNSBLs out there. I've used them over years and have had superb performance and very effective spam filtering. If they blocked off someone, it's a very rare possibility that the message is good. </div>
<div> </div><div>We did maintain a positive whitelist to ensure our key clients dont get "filtered" out though; but thats a different matter... Spamhaus had put up something about a whitelist they're working on; which I think was invite-only when I last checked.</div>

In the over a decade spamhaus has operated I have not seen spamhaus people take a single penny from anyone at all in matters to do with listing or removal of IPs.<br>
<br>
Did you get listed by spamhaus ever? I am not counting any of the dozens of poorly operated blocklists out there, most of which have one guy and his family dog using them compared to spamhaus that has a footprint of billions of mailboxes across ISPs, civil society organizations, industry and individuals with their own mail servers using it.<br>

I recall the case of the infamous Barracuda, which sells antispam software, as the first to try and extort money from us. Since we protested in quite strong terms and made a bit of a noise, they left us alone. But there are plenty of others.<br>
