Authentication-Results header (set domain only instead of fqdn)

[Engels, Jan]

Hi everyone,

is it possible to tell amavisd-new to set the Authentication-Results header
to the domain only (instead of the machine's fqdn)?

Example:

We currently get:
Authentication-Results: spamfilter1.desy.de (amavisd-new);
	dkim=pass (2048-bit key) header.d=gmail.com


We would like to set:
Authentication-Results: desy.de (amavisd-new);
	dkim=pass (2048-bit key) header.d=gmail.com


Background is because we would like to activate ARC-Headers in our sympa mailing
list servers (www.sympa.org) and it's configuration expects this.


Cheers
Jan
