    Also, if your domain doesn't receive mail, set up a null mx record: @ IN MX 0 . https://datatracker.ietf.org/doc/rfc7505/

    The text is added to get around bayesian filters. The spammer doesn't want the text to be displayed to the end user though typically.

    That wouldn't be better guidance. That would be additional guidance. I'm sure Google also never let anybody set up postmaster@gmail.com

    I wasn't able to sign up for postmaster@rootshell.is, but I was able to get abuse@rootshell.is. You should be careful about what standard email addresses you allow people to take. …

    You declare HSTS preload, but you are not in the preload list. You can not be added to the preload list at https://hstspreload.org/ because www.rootshell.is exists but has an inval…

    Weirdly, if I click Load Images, all I get is a load more CSP errors and the image fetches don't happen.

    You defeated https://www.emailprivacytester.com straight off. Which is more than most new email services. You seem to be relying on CSP entirely for this, but it works.

    Targetted automated spam, most likely written by an LLM you say. By any chance do you see the text "agentmail" anywhere in the headers/body of that email?

    Are you unaware that scalpers are set up to hoover up as many tickets as possible before an actual person that wants to visit the event can get one? Because it seems like you are?

    Comment #48234606

    The "market price" you're talking about, is set by how many scalpers are creating scarcity. If the number of scalpers is 0, then the "market price" is different. It becomes the pri…
