My guess would be that's just their login, but their email would not have their location sub-domain (I've never seen a sub-domain in e-mail, well actually not true, people with domain + country TLDs all have it, e.g. [e-mail]).

Of course moving locations/departments would mean getting a new login which is all sorts of problematic.

Lots of older companies still have subdomains in email, left over from when that was actual machine to route to.

I use pi4.navan.dev for my emails, while I’m getting the rDNS stuff figured out with my ISP.

No reason, but it just signifies that the mail server is hosted on my pi4 at my home, while I host navan.dev on a VPS

There’s no reason to do that, though. You can set your MX record to whatever you want for your domain. Why would you set yourself up to have to change your email? Not to mention advertising that your email is on a raspberry pi. Somebody will probably come along and DDOS that thing just for fun.

I just use that as a disposable email. I know there are better ways, but then with a subdomain, I can just experiment as much as I can.

I would like to believe that I have put the correct measures to prevent a DDOS attack, and it’ll be fun to combat a real time attack honestly
