Hi
I have a working installation of amavis 2.13.1 on Fedora 42 which
currently is set to do DKIM signing and validation via spamassassin with
DKIM plugin which adds the Authentication-Results header to inbound
email. The relevant amavis setting is:
$enable_dkim_verification = 1
DMARC plugin is also apparently enabled as well as SPF and DKIM plugins
and I see hits for SPF and DKIM rules in the X-Spam-Status header of
incoming emails.
If I want to add DMARC validation. Can that only be done by adding an
external checker like openDMARC? I was just wondering if there was a
reason not to have validation within the SPF and DMARC plugins with
amavis settings like:
$enable_spf_verification = 1
$enable_dmarc_verification = 1
(which don't currently exist as far as I know), updating the
Authentication-Results headers for DKIM validation?
Thanks
John
