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'm in your situation and what I do is relay my email through Amazon SES. It's unlikely to get blacklisted and it's cheap. Costs me literally $0.01/mo to use.

On the inside I have a postfix server all the systems are configured to send through. The postfix server is set to relay all messages to SES. You also need to make sure that SES is configured in your domain SPF record.

EDIT: I just re-read your message. If all you're looking for is outbound email, mailcow is significant overkill. All you need is an MTA like postfix.
