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?

    the simplest option is probably to just have Postfix deliver into a local mailbox and access that over IMAP

    I already have sendmail on the server. Is there something special about Postfix? Just asking,I’ve never run Postfix and I’ve never had this experience before with a host. I guess they think that if they charge an extra 6 Euros to flip the switch, people wouldn’t use it for spam purposes. I’m bound and determined to figure out a workaround just because.
