Hello all I successfully installed SOGo (nighlty build) and happily using it on a SAMBA AD/DC environment with 2 domains. FYI I moved to SOGo after using for many years a different platform, but I kept using postfix/dovecot/rspam as backends. All SPF/DMARC/DKIM were been properly set and are correctly running (both in terms of DNS and in terms of scripts), but now I am facing some inconsistencies:
If I send email from SOGo Web Interface, then DKIM signature on the recipient side appears valid, while it is invalid if I send it via Outlook (and yes, I do connect to SOGO via Active Sync on MS machines). How is that possible? I googled it and it appears that via Outlook SOGo is not able to flag as originating the email to be send, but not sure how to fix this. Any suggestion pls? PS. No significant log from rspam to help me in finding the root of the issue (which, in a sense, it is what I would expected since the email via outlook seems to miss completely the signature process...) Thank you G
