It sounds like your server provider isn't allowing you to send emails or you have some kind of firewall or network issue. You should contact your server provider to ask what is happening.

If you're seeing that error after adding a new IP to your IP Pool, it’s likely due to incomplete configuration – especially missing DNS or PTR records, or the IP not being properly assigned on the server level.

I wrote a full guide that walks through everything you need to do when adding additional IPs in Postal: assigning them to the server, configuring DNS (including SPF and PTR), and setting up the IP pool properly.

Here’s the guide if it helps: How to Use IP Pools for Better Deliverability in Postal

Let me know if you get stuck on any step.
