    Functionality, features & more

    Protect your clients’ inboxes from spam, viruses, phishing, harvesting and other malicious threats. The clustered solution adds another redundancy layer to your network. SpamExperts manages the software and monitors all servers and services 24×7 to proactively fix any issues that might occur.


    SpamExperts uses an advanced proprietary IP-reputation system, combined with a large number of message content classifiers. Incoming email filters have an industry leading rate of nearly 100% filtering accuracy with a very low false-positive rate.


    The incoming anti-spam system adds another failover layer to your infrastructure. If your client’s destination mail server is down, the inbound filter will still accept messages and queue them. They will be automatically redelivered, and can be web-based previewed by clients while working.


    SpamExperts solution helps you save the infrastructure and human resource costs needed to maintain open source solutions.

    IP reputation

    By properly filtering all outbound spam, viruses and malicious attachments which would have otherwise left your network, you assure a solid IP reputation and avoid blacklisting issues, costs, and annoyances.

    Company reputation

    Blacklisting prevention does not only secure your IP, but your company’s reputation as well. Your organization and network will be regarded as trustworthy and safe.

    Continuous mail delivery

    Securing your IP reputation and timely locking down compromised accounts assures delivery of your outbound email. There is nothing more frustrating, time consuming, and expensive than undelivered email to the recipients’ inboxes, due to low network reputation.

    Abuse manageability

    SpamExperts outbound filtering solution allows you to automatically lock compromised accounts and/or quickly respond to ARF reports, generated by SpamExperts systems, on detected abuse from your network.

    Offering professional compliance services is a real money-making tool and reduces the total cost of e-discovery. SpamExperts helps with various hashing and encryption technologies. Archived emails are always stored in an encrypted and compressed format and are easy to retrieve in a migratable and open format.

    Data redundancy

    Two methods of storing your archived data available. Encrypted and compressed archives can be striped or mirrored and stored on multiple storage servers, providing maximum data redundancy.


    Even if your destination mail server is down, SpamExperts system will continue to archive emails for you. Decide for yourself how long you want to archive your messages for.
