aDNSBL Advantages

Enables the quick filtering of inbound email traffic by rejecting connections from remote IPs that are present in aDNSBL.

Reduces significantly (up to 80% of inbound email traffic for well established domains) the processing of content filters, thus optimizing hardware resources.

Built in whitelists ensure that Axigen will make sure that no large senders will get on the list, thus reducing the false positives to a minimum.

Further enhance your spam fighting with a content filter (i.e. Axigen Premium AntiVirus and AntiSpam) to ensure best protection for your users.
