I have a couple Docker containers that use email as an alert system or just for info like completed jobs. The server I would like to host them on has, for whatever reason, blocked email ports and you have to pay extra to have them turned on.

It seems to me tho, that I should be able to port all email through Tailscale to a local or even remote email client. For instance, in the case of setting the parameters in the Docker compose, it would look something like this:

SITE_NAME: mycoolwebsite
DEFAULT_FROM_EMAIL: email address
EMAIL_HOST: smtp
EMAIL_HOST_USER: email address
EMAIL_HOST_PASSWORD: email password
EMAIL_PORT: 100.x.x.x:587

Then, configure the local email client to listen on 100.x.x.x:587.

Would this be doable, or is there a better way?

    If you control both sides, you can just use a non-standard port. If you only control the client, you just need to make sure wherever your data exits allows outgoing traffic on that port.

    So yeah, that should work.
