Automating SMTP Port Management Across VPS Nodes: A Step-by-Step Guide for Virtualizor based KVM VPS
Most of the providers must be already having a solution to manage SMTP Port on their VPS Nodes, but still some providers might be struggling with it, especially when you need to manage enabling or disable SMTP Port manually and keeping track of when to again block the SMTP Port once the VPS is terminated or IP assigned to another client, so I've worked on an automated solution that works with Virtualizor and WHMCS, you can probably update it as per your requirement if you are using some other panel or some other billing system.
this setup will automatically remove IP from whitelist once a VPS is terminated.
It's working without issues for me with about 140+ VPS Nodes.

I hope it will at least help some new providers.
