hi everyone,

I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.

Is that true?

(I’d not seen much about that in stuff I’ve looked up so far about self hosting)

      PTR lookups has been a thing for email servers for a very long time… “used to work fine” would have been early 2000’s as far as I can remember.

      PTR is de facto requirement for over 20 years now. So unless you’re talking about pre-turn of the century, not really… email servers haven’t worked without PTRs for a very long time.

      I had to look it up, but Yahoo and AOL implemented PTR checks in 2003-2004. Gmail had it out of the box in 2004.

      Can you run a server without it? Yes… and it will work with any other server that doesn’t mandate valid PTR records. But no major consumer email server has supported receiving mail from a PTR-less server for 20+ years now. So you’re not going to be able to email basically anyone from your server.
