--- Comment #1 from Tim Mohlmann <muhlem...@gmail.com> ---
Same problem here. Arch Linux with KMail 5.14.0. Verified with KMail on 5.13 on
Kubuntu and bug does not exist there.

In fact, the smtp "envelope from" is empty. In my case this is causing all
outgoing mail not being DKIM signed by the server and rejected by bigger
hosters like Gmail.

A logs from the sever:

mail postfix/smtpd[15514]: connect from

Notice that the from=<> is empty.

On the receiving side header look like:

The From in the body is set, but envelope from is empty.
