Hello everyone, I am wanting to host a email server for the fun and for sending emails in my selfhosted apps but don't want to port forward, cf is out the question for what I know so is zrok a option? Have someone done it?

It's a great option and I know one person that did it already. I guess it's a matter of configuring some MTA to send and to listen as an open relay, then use zrok to control access to the MTA's listening port.

You could run the zrok-share Linux service on the MTA host pointing at the listening port as a tcpTunnel target. Then you could run a private access on the hosts that need to send email.

There's [a Docker private access example here](https://docs.zrok.io/docs/guides/docker-share/docker_private_share_guide/#access-the-private-share) you could use if the sending hosts have Docker. There's not a zrok-access Linux service yet, but it wouldn't be too complicated to [make one if someone's looking for a little project](https://github.com/openziti/zrok/issues/698).

```bash
sudo -E zrok access private smtpsharetoken --bind 127.0.0.1:25

```

Really sorry for not answering you I didn't remember this but well, zrok doesn't do public tcp tunnels right? If not this is not possible

Yes. You can self-host a "personalized frontend" to provide a public TCP proxy for a specific zrok private share.

> **[Personalized Frontend | Zrok](https://docs.zrok.io/docs/guides/self-hosting/personalized-frontend/)**
>
> This guide describes an approach that enables a zrok user to use a hosted, shared instance (zrok.io) and configure their own personalized frontend, which enables custom DNS and TLS for their shares.
