Amazon EC2 Cloud spammed

[bmw]

This just in from our anti-spam/-virus proxy, Death2Spam.net:

System Status Notification: A spammer got the entire Amazon EC2 cloud black-listed on Spamhaus yesterday, despite Amazon's zero-tolerance spam policy, causing disruption to (some) email deliveries from our SMTP servers. We have applied for immediate and permanent de-listing, and meanwhile, D2S is queueing all RBL-blocked messages. To obtain immediate delivery, customers should suspend spamhaus.org from any DNSBL checks performed by their domain's mail server, or explicitly white-list our IP addresses [75.101.155.29, 75.101.128.14, 75.101.133.30] so they're exempted from RBL lookups.

Where is the global or RBL adjustments in ZCS server that needs to be made?

RBL's are configured in Global Settings -> MTA tab -> DNS Checks section
