SYNRBL

Approximately 14.5 billion spam emails are sent each day globally. While most spam traffic is stopped at the SMTP level, spam still makes its way into peoples inboxes. We have created this RBL service as an extra means of protection. Any IP addresses that pass through the SMTP layer will be blocked if they match a blocked IP addresses submitted to SynRBL.
