Latest SBL Changes
SBL89504 is not in the SBL.

This may be because SBL89504 has been resolved and removed from the SBL.

The SBL DNS zone is refreshed every 10 minutes and broadcast to 60 Spamhaus DNSBL servers in 14 countries. If you are still experiencing a block on your mail by some providers a few hours after seeing this 'not in the SBL' message, your IP is probably blocked by some other DNSBL system.
