When sending email, does Evolution include IP address (or any other identifiable information which would not be included if I sent the same email through browser) in the headers?
I presumed that this would depend on the email provider. However, Proton, for example, says that they hide IP addresses when sending through their website or native client, but that using external clients may reveal IP address of the sender through header.
The email headers of messages sent from Proton Mail web and mobile apps don’t contain user IP addresses in the headers of sent mail.
But desktop email apps that use SMTP, like Outlook or Thunderbird, may include the originating IP address in the header.
I want to know if I can trust Evolution to never do this.
Hi,
Evolution doesn’t do that, but what the SMTP (or generally sending)
server does is up to it. Evolution identifies itself when talking to
the SMTP server. You can override the SMTP value for all the SMTP
servers with:
gsettings get org.gnome.evolution-data-server camel-smtp-helo-argument
(the command returns what you’ve set there).
It’s easy to check what Evolution sent, just send yourself an email and
when it’s received, view its source, with Message->Source or simply
Ctrl+U.

In such case, the source shows headers relating to: client sending, email provider sending, client receiving, email provider receiving.
Do you know how I can distinguish these? I want to know what the recipient receives from the sender, not what the recipient receives from its own email service provider.
From there, it would be nice to know if any of the data pertains to Evolution specifically, rather than the outgoing SMTP server.
You can look at a message in your local Outbox to see which headers Evolution sets. Evolution cannot guess which headers your mail provider or other mail providers may add or not.
Hi,
just in case, for that, use Edit->Preferences->Composer Preferences
->Send through Outbox folder option. Note the headers starting
with X-Evolution are removed before the message is sent.
Bye,
