Hello, does anyone know how I can display the X-Mailer in the Kmail header?


I've tried a few things:


1. In the kmail2rc file I added under [Reader]: ShowUserAgent = true

DID NOTHING (no matter which opening credits I choose)


2. I changed the header theme file and added the variable header.xmailer.

UCH THAT DIDN'T WORK. What I added:

<div class = "headerleft"> X-Mailer: {{header.xmailer}} </div>


Does anyone have any idea what I did wrong or how to get the X-Mailer displayed in the opening credits?

I use KMail Version 5.19.0 (21.12.0). I tried several headers: decorative, standard, standard-grantlee - no difference.
