Questions before you buy.
Will it block legitimate newsletters?
You can whitelist accounts and set higher caps for senders you trust. Blocks are logged and reversible from WHM.
Does it slow down outgoing mail?
No. It counts messages in the Exim queue path and adds no measurable delay.
Which cPanel & WHM versions are supported?
cPanel & WHM 11.110 and newer on AlmaLinux 8/9, Rocky Linux 8/9, CloudLinux 8/9 and Ubuntu 22.04. We test every new cPanel release.
How is the license counted?
Per server IP. There are no per-account or per-customer fees, so your costs do not grow when you sell more hosting.
What if the plugin does not fit my setup?
Ask for a refund within 30 days and we return the full amount, no questions asked.
