Hello everyone,
I use mailman together with mailcow and have configured my mailing list as follows:
- Anonymous list: Yes
- DMARC mitigation action: Replace From: with list address
- DMARC Mitigate unconditionally: Yes
My problem is that my emails are not being accepted by mailcow (rspamd) with the error SPOOFED_UNAUTH (50.00) ... What am I still doing wrong? Can you help me, which setting is still missing? What informations are you still missing?
I doubt that this has anything to do with the ARC-*, Authentication-Results or DKIM-Signature headers you quote.
There are some threads on SPOOFED_UNAUTH in the mailcow community forum, e.g. https://community.mailcow.email/d/403-spoofed-unauth-rspamd and https://community.mailcow.email/d/637-problems-with-emails-keep-getting-reje...
Also see https://www.reddit.com/r/mailcow/comments/12lhw8e/whitelist_ip/
These came up in a google search for SPOOFED_UNAUTH.
