Comment on It will be great, they said...
ysjet@lemmy.world 1 week agoYou do realize your DNS MX records can point to both IPs, and your primary connection just has a higher priority number, right? This is 2025, dns is outright expected to have multiple IPs behind in varying levels of priority and availability.
As for DDNS constantly rolling things, I’ve got, as I said, spectrum residential and my IP address has changed once in half a decade.
Finally, I literally mentioned that there were other ways around this, like an external proxy server on a static IP. Throw it on DO or something.

Hm, I’m gonna remain skeptical.
Using the random ip you get from mobile data or using dynamic dns feels risky. Maybe that’s because I’m not smart, but the whole trust level is mail thing seems very heuristical and the risk of damaging my domains trust factor doesn’t seem worth it.
I’m not skeptical about having two ip addresses, but rather using ones that I don’t have control over (i don’t have the only right to use).
I might be wrong on the PTR record thing, seems it might be possible with DDNS providers but not 100% sure.
