Versions
Delta Chat 1.8.1 for Android (F-Droid)
Delta Chat 1.4.3. Desktop (AppImage)
Header messages coming from DC clients with provider Disroot are leaking IP number and machine name on desktop and IP number on Android.
Expected behavior:
The IP and machine name on the headers should be stripped or masked as it actually happens with other providers like Posteo, mailbox. org, vivaldi…
On the other hand, Messages sent from Disroot webmail service do not expose the IP nor the machine name.
Actual behavior:
Please, see the following headers fragments I’m pasting

Steps to reproduce the problem:
Sending messages from Delta Chat App with disroot. org as provider to any available email client where you can read headers should do the trick.
Thanks in advance and best regards to you all!
