I’m still mildly annoyed every email I send using Mail has my IP embedded in it

This is your email provider doing this. I use Fastmail. Fastmail does not log the IP of the sender when you use its SMTP servers.

Source? I don't think this is true. Doesn't seem to be the case for me. Maybe your email provider attaches your IP address?

    Seems like this is a Gmail thing: https://ylukem.com/blog/apple-mail-leaks-your-ip-address

      It's not a Gmail thing:

      > The reason why my IP address is visible is because Apple Mail sends emails with SMTP.

      Unless you use a proxy, your IP address is visible to an SMTP server, just like it's visible to an HTTP server when you use a web browser. This is not specific to Apple Mail or to Gmail.

    It’s in the headers. Send an email to your self from Mail and open the source in the inbox. There is your IP.

      I also just tried this as well, sending an email from a Migadu-based account to one at both Gmail and MXRoute using Mail.app under macOS 15.7.7. Neither included any private IP address info I could find in either headers or raw source. That would be a good leak to know about and as sibling comment said saagarjha definitely knows their stuff, so any tips to replicate would be appreciated.

      Is this from iOS? I just tested from MacOS, and the only IPs were for the transit and auth servers.

      I'm not actually doubting it. saagarjha knows his stuff. I just don't see it, so maybe I'm holding it wrong.
