Once they know what hosts you run, it'll ping that hostname periodically. If it stays up and stable for a couple days, you'll get an alert in product: "Set up uptime monitoring on ?"
Whether you think this is valid, useful, acceptable, etc. is left as an exercise to the reader.
Having recently set up sentry, at least one of the ways they use this is to auto-configure uptime monitoring. Once they know what hosts you run, it'll ping that hostname periodically. If it stays up and stable for a couple days, you'll get an alert in product: "Set up uptime monitoring on ?" Whether you think this is valid, useful, acceptable, etc. is left as an exercise to the reader.

> Admittedly, most residential ISPs block all SMTP traffic, and other email servers are likely to drop it or mark it as spam, but there's no strict requirement for auth. Source? I've never seen that. Nobody could use their email provider of choice if that was the case.

I think its more the nuanced difference between safety and security. Engineers build things so they run safe. For example building a roof that doesnt collapse is a safe roof. Is the roof secure? Maybe I can put thermites in the wood...
this is the difference. Safety is no harm done from the thing itself Engineers build and security is securing the thing from harm from outside.

Well I am not in the USA for a start but if it is blocked it must be only inbound otherwise it would break everybody.
Yep, at least in France it's like this for ISPs doing this IIRC.

NAS is the primary function. But yes, I want full linux server that I can decide what to install and which protocol to use to upload and/or download files.
Why not just leave the NAS to be a NAS and get a separate server? You're probably better off not trying to overload the NAS to be everything.
