What I'm wondering is this: Why is it a problem if your IP address is
disclosed? Maybe if you're a dissident in an authoritarian society,
but in Canada? I don't see it.
For me, when I ran some web servers on my home IP, I felt it preferable
to refrain from disclosing my IP in every email. Not a huge deal, just
preferred.
When I finally implemented the feature though, it was mostly a learning
process for Postfix.
If a government agency wanted to find my IP address, they would do so by ordering my ISP to disclose it.
Well, if the IP isn't in the headers, they wouldn't know which ISP to
approach.
But then they'd just see who controls the server first in the list of
Received-From and demand account info from that provider. Basically,
I'm agreeing with you re: nation-state level investigators.
And there are a million other ways to find out your IP, not the
least looking at server logs if you happen to visit a government
website.
Tying a specific visitor to an email header IP would take a lot more
effort if the ISP-assigned IP is stripped from the headers.
Again, pretty much agreeing with you on all points but at least I'm a
wee bit more protected from DDoS when that originating IP is stripped
out. And, I learned something doing it and that's the real bonus.
Cheers!
