Four static IPs with Reverse DNS and open port 25 outbound, for mail server?

[Falkvinge]

Good morning,

I've grown tired of my current ISP's so called "static IP" and I'm looking for alternative solutions. When I get static IPs from you (4×IPv4, plus a static IPv6 block of at least /56), does that also come with the ability to set reverse DNS lookups, and can I initiate traffic outbound through these static IPs with port 25 open, so I can have a fallback egress for my mail server?

(My current ISP has been down for a week, so mail has been patiently waiting but it's also not getting delivered, and that has me quite annoyed.)

Cheers,
Rick

Hello,
We don't offer that. For this project, you should find a provider to host a server or get a professional connection from an ISP with the parameters you require. You can also contact our support team about this at support@feste-ip.net.
