DirectAdmin uses the same one-line installer as cPanel; it detects the panel by itself. As root over SSH:
curl -fsSL https://iam4hosts.com/get | bash
Then open Extra Features → Inactive Account Manager at admin level.
- The plugin installs under
/usr/local/directadmin/plugins/iam4hostsand runs at admin and reseller level. - Admin accounts see everything; resellers see only the users they created. End users have no access.
- Suspensions carry the reason "Suspended by Inactive Account Manager", so the plugin recognises its own and never touches accounts suspended for other reasons.
