--- Comment #7 from Giovanni Bechis <giova...@paclan.it> --- ARC is not required by DMARC, on DMARC plugin, ARC signatures are checked only if DKIM check fails and they are read from Mail::SpamAssassin::Plugin::AuthRes plugin if the plugin is enabled. Which ARC signature you trust can be configured on Mail::SpamAssassin::Plugin::AuthRes plugin. -- You are receiving this mail because: You are the assignee for the bug.
