Hi, I had 'dkim_verify_minimal = true' in my Exim config and according to https://www.exim.org/exim-html-current/doc/html/spec_html/ch-main_configuration.html "If set to true, verification of signatures will terminate after the first success.".
But this does not seem to be what is happening and that in turn breaks DMARC checks. Exim 4.96, libopendmarc2 1.4.2 I put this acl_smtp_dkim in: | acl_smtp_dkim = acl_check_dkim | | acl_check_dkim: | warn | logwrite = DKIM--$dkim_verify_status--$dkim_cur_signer--$dkim_verify_reason--$dkim_domain--$dkim_identity-- | | accept And with a message that has multiple DKIM sigs i get: | LOG: 1sQq1q-00BKvo-0I dkim--pass--bf02x.hubspotemail.net----bf02x.hubspotemail.ne...@bf02x.hubspotemail.net-- | LOG: 1sQq1q-00BKvo-0I dkim--pas...@bf02x.hubspotemail.net----bf02x.hubspotemail.net-...@bf02x.hubspotemail.net-- | LOG: 1sQq1q-00BKvo-0I dkim--none--lease-a-bike.nl----lease-a-bike.n...@lease-a-bike.nl-- | LOG: 1sQq1q-00BKvo-0I dkim--non...@lease-a-bike.nl----lease-a-bike.nl-...@lease-a-bike.nl-- | LOG: 1sQq1q-00BKvo-0I DMARC results: spf_domain=bf02x.hubspotemail.net dmarc_domain=lease-a-bike.nl spf_align=no dkim_align=no enforcement='Reject' Notice the 'none' result in $dkim_verify_status. I am almost certain this is what breaks DMARC because when i set 'dkim_verify_minimal' to 'false', i get: | LOG: 1sQq2w-00BKyE-0A dkim--pass--bf02x.hubspotemail.net----bf02x.hubspotemail.ne...@bf02x.hubspotemail.net-- | LOG: 1sQq2w-00BKyE-0A dkim--pas...@bf02x.hubspotemail.net----bf02x.hubspotemail.net-...@bf02x.hubspotemail.net-- | LOG: 1sQq2w-00BKyE-0A dkim--pass--lease-a-bike.nl----lease-a-bike.n...@lease-a-bike.nl-- | LOG: 1sQq2w-00BKyE-0A dkim--pas...@lease-a-bike.nl----lease-a-bike.nl-...@lease-a-bike.nl-- | LOG: 1sQq2w-00BKyE-0A DMARC results: spf_domain=bf02x.hubspotemail.net dmarc_domain=lease-a-bike.nl spf_align=no dkim_align=yes enforcement='Accept' And DMARC passes too. Is the 'none' result expected? The fine manual seems to suggest it is not. There was a pass so no more validation should be attempted? Did i hit a bug here? My assumption of the verify_minimal option was some sort of 'satisfy any' instead of 'statisfy all' functionality.
