I’m going to travel abroad, and I’ll receive emails there(via IMAP/POP). But I don’t want to let my email provider learn that I’m abroad, nor to let foreign ISPs learn that I’m using email. My email provider blocks tor.
So, I’m going to use Bitmask (Riseup VPN) with “snowflake” option (so ISPs can’t know that I’m using Riseup VPN?).
Is this a good idea?
So, I want to hide
Then at that point, do you trust your email provider? Privacy focused email providers won’t even care about this data.
Could be done, but this is really only for censorship. If the foreign country is heavily censored, it probably is a good idea.
A VPN like Mullvad, Proton, IVPN, or Riseup is all you need if it is a concern. If you really need to, Tor is also an option.
Set up a server at home and just use Tailscale?
Basically set up a computer that is pretty much a server connected to a router that can send Wake-on-LAN packets (just in case you get a power failure at home if you dont have a UPS).
Have Tailscale installed on 3 devices:
You can have an operating system of choice on the server and either do a remote desktop connection to it or use SSH to log in to and retrieve the message via CLI (as with something like CLI Protonmail Bridge).
Power failure can happen, so set your router to turn on as AC power returns so you can send a Wake-on-LAN packet to your server to also turn it back on and check your email.
get a travel router Beryl AX (GL-MT3000) works great. Route all traffic through TOR, or a VPN of your choice. That would be my first step.
Calyxinstitute.org sells mobile data hotspots that are anonymous, not tied to your identity.
Combine those two things together and you are ghost, given your continue to use proper opsec.
The carrier will still have your accurate location and can easily correlate that with other active or past devices in the area.
