[Rspamd-Users] DMARC Status in the absence of DKIM

[Marco Pizzoli]

Hi,
the involved domain has a DMARC policy of "none", so it is expected.
https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3akontaktybiznesowe.pl&run=toolpage

The status reported in your email confirms this as well:
dmarc=pass (*policy=none*) header.from=kontaktybiznesowe.pl;


Regards
Marco
