Not very familiar with self hosted emails, could you explain how the subscription emails work? How does putting the website before the @ work? Does your email server then forward those emails to the corresponding family member since I’m guessing the email address doesn’t exist before subscribing.

i use mailinabox on a cheap vps. 10-20 minutes install no problem. what the poster meant was [e-mail] here 12 is family member code and hackernews is the actual website where that person is trying to get registered.

this is pretty awesome setup because if you get spams from anyone, you can simply see which family member signed up for which website and which one is leaking data. the next step, if required would be to delete that account/email and be done with it. no more spam, no more going back. If you do need that email in future, recreating it would be trivial, like if you need to get back into an old account or the like

Each family member has a subdomain all to themselves. The website before the @ allows them to know where the sender got the email address from. You can have catch-all addresses on emails, so anything without a mailbox is sent to the default mailbox that's configured.

It need not be self hosted to do this. Most email providers provide this functionality.

That's exactly right. I don't self-host the email (you can use any service that takes catch-alls like mailbox.org).

anything '@subdomain' gets forwarded to its respective family member's email.
