[Rspamd-Users] from (Header | SMTP)

[Huber, Peter]

I changed this a few weeks ago, but this does not solve the problem

# Domain to use for DKIM signing: can be "header" (MIME From), "envelope" (SMTP From) or "auth" (SMTP username)
# use_domain = "header";
use_domain = "envelope";

Test:
x-sender: peter.huber at uni-wh.de
x-receiver: test-794d4411 at appmaildev.com
From: BIT-Support an der UW/H <BIT-Support at uni-wh.de>
To: "'test-794d4411 at appmaildev.com'" <test-794d4411 at appmaildev.com>
Return-Path: peter.huber at uni-wh.de
DKIM-Result: fail (bad signature)

Any idea?

Kind Regards

Peter Huber

# Domain to use for DKIM signing: can be "header" (MIME From),
"envelope" (SMTP From) or "auth" (SMTP username)
use_domain = "header";


Does that help? You probably want to set

use_domain = "envelope";
