Iberwall Hosted Filtering - How does it works?

Iberwall Hosted Anti Spam Filtering for Email Servers

With a simple change at your DNS servers, pointing the MX record at our network, your email company will be protected by our Anti Spam, a cloud based solution, including SMTP Relay or Smart Host, to avoid potential blockage of ports and IPs caused by DNSBLs where your IP address range could be included.


Iberwall Hosted Filtering operates on a network that contains fault-tolerant servers with Redundant WAN lines, including load balancing, QoS policies. In the unlikely possibility that one of the lines is unavailable, traffic is automatically routed to any of the other networks with full transparency, minimizing the possibility of any interruption in the service.
