Resolved DMARC policy none but mail rejected

[papak]

Hi,

From time to time are some mails from valid senders rejected with:

DMARC: REJECT message for [email protected]
message discarded by a mail handler

In Plesk is DMARC policy set to default: V=DMARC1;p=none

Example from maillog:

Any hint how to see why and what is going on?

Thanks in advance.

I found this:

Cannot send messages between internal mailboxes: DMARC: REJECT message

but I'm having issues with external mails and Plesk is up to date.

Isn't the DMARC policy you quoted for outgoing mails only? Incoming mails will still be checked when enabled, and therefore might fail, maybe because your mails are going through antispamcloud, which breaks SPF?
If you are trying to do what I think you are, you should disable all checking for mails coming in by antispamcloud.
