The only problem with zen.spamhaus.org is this statement, found on
http://www.spamhaus.org/zen/index.lasso :

"ZEN Usage

Use of the Spamhaus DNSBLs via DNS queries to our public DNSBL mirrors
is free for low-traffic mail servers serving less than 100 users. Use of
the Spamhaus DNSBLs by commercial users, including corporate networks,
ISPs and ESPs, requires a subscription to Spamhaus's Data Feed service."

Cheers,
