Monitoring Tools Monitoring software for mail (smtp)?

Do you guys know any tool which monitors SMTP and also checks if the IP addresses are on any blacklist?

I use MxToolbox right now, and get a weekly summary, but it's kinda "annoying". I only need an alert when something is wrong and then immediately.

yeah honestly for real time alerts Iā€™d probably look at Uptime Kuma and blacklist checks or HetrixTools fr šŸ˜­

weekly summaries are useless when your SMTP reputation dies overnight

Thanks! HetrixTools seems good. Free SMTP and Blacklist checks. I'll try it out
