Issue whitelisted sender still going to junk

[Ksech]

An external domain beyond my control... fails spf and dmarc...
whitelisting gives them a negative spam score but the emails still go to junk folder
I've lost sleep over this!
Is there a way to override this behavior for a specific server address?
If not, would turning off spf checking for incoming mail fix it?

This is a form being sent from another server, and it's a mess, but we need to get these emails without having to dig through the junk folder. Here's a maillog snippet:

The DMARC settings seem to indicate domain spoofing. That is a different check from the SpamAssassin whitelisting. For testing purposes you can try to deactivate the "Enable DMARC to check incoming mai " option in the mailserver settings. Your mails will likely pass afterwards.

DMARC checks whether DKIM and SPF records of the sender's email source are correct (match the authorized sender's server). If the check results in "incorrect", DMARC reads what it shall do with such mails from the sender's domain. In your case, the sender's domain has set that to "p=quarantine".

Thank you Peter - I will try that!
