Description sedrubal 2019-09-08 19:40:40 UTC 
SUMMARY
kmail generates message IDs using a random string and @<hostname>. There may be cases where you don't want to tell your hostname.

STEPS TO REPRODUCE
1. Write an E-Mail
2. Send it
3. Inspect its sources

OBSERVED RESULT

The Message-ID is something like <$random@$hostname>

EXPECTED RESULT

There should be at least an option to make the message id anonymous.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 30
KDE Plasma Version: 5.15.5
KDE Frameworks Version: 5.59.0
Qt Version: 5.12.4

ADDITIONAL INFORMATION
Additionally it would be great to hide the following headers:
- X-KMail-Identity
- X-KMail-Transport
- X-KMail-Fcc
- X-KMail-Identity-Name
- X-KMail-Transport-Name

- X-KMail-Transport-Name
it's removed when we send email. It's just keep when it's stored in local.
So this one are not a problem.

The Message-ID can be tuned:

Settings / Configure KMail / Composer / Headers
"Use custom Message-ID suffix"
