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.

    Potential problem on the incoming side as well is that if an SMTP server is running on whoever gets the old IP, they may accept the delivery and it may end up on someone else’s catchall handler too. So not just delivery problems and potential delays lost mail, but it can also get successfully delivered to a completely unknown third-party.
