Good day Victor (and Jeremy!), Thanks for your advice, super on point regarding the issues I've been facing. I've had this project on hold for awhile and just picking it up now so apologies for the tardy response.
I was sceptical about building Exim with ARC authentication - being an experimental feature and not widely adopted anyhow, so I'm glad there's a workaround to disable arc authentication in opendmarc. I've patched opendmarc and exim and also updated the opendmarc SQL as you've recommended. The opendmarc patch and SQL modifications are working like a charm! However unfortunately the exim patch hasn't resolved the lack of SPF/DKIM details being logged to the dmarc history file. Sorry to trouble you further, but do you have any other ideas? here's a debug output from Exim for a delivery: https://pastebin.com/iZEiEHu9 The corresponding delivery log in the dmarc history file: reporter server.hostname.com.au received 1692234968 ipaddr 209.85.215.171 from gmail.com mfrom gmail.com spf 0 dkim gmail.com 0 pdomain gmail.com policy 15 rua mailto:mailauth-repo...@google.com pct 100 adkim 114 aspf 114 p 110 sp 113 align_dkim 4 align_spf 4 action 2 And also the delivery information in the exim mainlog: 2023-08-17 11:16:06.760 [2565238] SMTP connection from [209.85.215.171]:56649 I=[103.209.24.57]:25 (TCP/IP connection count = 1) 2023-08-17 11:16:07.591 [2565282] SPF validation passed 2023-08-17 11:16:08.276 [2565282] 1qWRcO-00AlLW-0O DKIM validation passed 2023-08-17 11:16:08.276 [2565282] 1qWRcO-00AlLW-0O DKIM: d=gmail.com s=20221208 c=relaxed/relaxed a=rsa-sha256 b=2048 t=1692234966 x=1692839766 [verification succeeded] 2023-08-17 11:16:08.561 [2565282] 1qWRcO-00AlLW-0O H= mail-pg1-f171.google.com [209.85.215.171]:56649 I=[103.209.24.57]:25 Warning: "SpamAssassin as sslreservedsite detected message as NOT spam (-0.2)" 2023-08-17 11:16:08.565 [2565282] 1qWRcO-00AlLW-0O DMARC results: spf_domain=gmail.com dmarc_domain=gmail.com spf_align=yes dkim_align=yes enforcement='Accept' 2023-08-17 11:16:08.567 [2565282] 1qWRcO-00AlLW-0O H= mail-pg1-f171.google.com [209.85.215.171]:56649 I=[103.209.24.57]:25 Warning: DMARC STATUS: accept gmail.com 2023-08-17 11:16:08.576 [2565282] 1qWRcO-00AlLW-0O <= macken...@gmail.com H= mail-pg1-f171.google.com [209.85.215.171]:56649 I=[103.209.24.57]:25 P=esmtps L.- X=TLS1.3:TLS_AES_128_GCM_SHA256:128 CV=no SNI= mail.demo-domain.com.au S=4704 M8S=0 DKIM=gmail.com RT=0.151s id=CAD2o6Gz8F= mvwjj0n0w-fdmxu8w7zavmsiya3r_f+eon42n...@mail.gmail.com T="test" from < macken...@gmail.com> for i...@demo-domain.com.au 2023-08-17 11:16:08.593 [2565296] cwd=/var/spool/exim 6 args: /usr/sbin/exim -d=0xf7795cfd -MCd daemon-accept-delivery -Mc 1qWRcO-00AlLW-0O 2023-08-17 11:16:08.730 [2565282] SMTP connection from mail-pg1-f171.google.com [209.85.215.171]:56649 I=[103.209.24.57]:25 closed by QUIT 2023-08-17 11:16:08.742 [2565296] 1qWRcO-00AlLW-0O => info < i...@demo-domain.com.au> F=<macken...@gmail.com> P=<macken...@gmail.com> R=virtual_user T=dovecot_virtual_delivery S=4923 C="250 2.0.0 < i...@demo-domain.com.au> wQpQKdh03WS2JCcAK/qN0w Saved" QT=0.470s DT=0.069s 2023-08-17 11:16:08.743 [2565296] 1qWRcO-00AlLW-0O Completed QT=0.621s Thanks again for your help.
