SYSBOXMX Radar
Round-the-clock watch on your mail servers' IP, DNS blacklist status and TLS certificates — with alerts the moment something breaks.
IP change detection
Every check resolves your mail server's current IP and flags it the moment it moves — often the first sign of a migration gone wrong or a hijack.
Blacklist (RBL) monitoring
Pick from dozens of DNSBL zones, weighted High/Medium/Low, and get notified the moment your IP shows up on one — before it hurts deliverability.
TLS certificate checks
SMTP, IMAP, POP and HTTPS ports checked for a valid, matching, non-expiring certificate — with a heads-up 14 days before anything lapses.
Alerts your way
Email, SMS, Slack, Pushover or a webhook — pick any combination of verified channels per server, no complicated profile setup.
Bronze / Silver / Gold cadence
Check every 24 hours, every 8 hours, or every 30 minutes — pick the tier that matches how critical each server is, per server.
Full history
Every IP change, blacklist add/remove, and certificate event is logged so you can see exactly what happened and when.
