cPanel® Irondome is an anti-spam filter that runs locally, but it queries the SPFBL.net database in real time. The filter is installed by our script and cPanel will be immediately protected. Our system will interact with sender and recipient to try to resolve suspect cases and avoid your support team be called. All email passing by the filter can be visualized and managed through the control panel.
All notorious spammers will be blocked immediately and they will receive a rejection warning message from our system.
In the case of a false positive, the sender will be able to ask for release and our system will contact the recipient to confirm it.
If the recipient agrees with the release, then our system will send a warning message to the sender explaining that he was accepted and can now resend the message.
All suspect messages will be held in the cPanel queue and our system will send a warning message to the sender informing that.
If the sender asks for the message to be released, then our system will contact the recipient to confirm it.
If the recipient agrees with release, then our system will request cPanel to release the message so that it can be immediately delivered to the recipient.
All released senders will be added in the whitelist, so any other future messages from the same sender will pass directly. System works in a peer-to-peer collaboration environment, which means it is refined with each human interaction.
