Hello everyone,

I am currently running a server with the Pterodactyl panel for various game servers, and it has been working great for several years. However, I would like to set up a system for Pterodactyl to send out password reset emails when necessary. I am considering using Mailcow on the same host specifically for this purpose. Currently, I am using an application named DDNS-Updater to automatically update all records on Cloudflare when my IP changes. While my IP doesn't change often, it can happen; it occurred once this year. Would this pose an issue for a mail server? If the emails end up in the spam folder, it is not a major concern since they are only password reset emails. However, it is crucial that the emails reach the intended recipients.

Thank you.

I use a wireguard tunnel and port forwarding from a vps to a mailinabox instance serving mail for my various domains. If you have your SPF/DKIM/rDNS set up correctly, it's not too bad with respect to management and mail delivery, plus you don't have to trust anyone with your data. As far as other mail servers are concerned, your VPS IP is the only IP they see. I pay $10/yr for the VPS
