[SOLVED] KAM_DMARC_REJECT outgoing mail

[ValentinDe]

Hello
I have a filter to block outgoing spam more than level 3. But today i see a new spam detect result for all mail on my proxmox mail gateway.
What is KAM_DMARC_REJECT ? And where is the configuration ?
Full line:

Jul 21 13:34:10 mail-gw01 pmg-smtp-filter[10709]: 60A7E5F16D2B1C6269: SA score=1/5 time=0.310 bayes=undefined autolearn=no autolearn_force=no hits=ALL_TRUSTED(-1),AWL(-0.037),KAM_DMARC_REJECT(3),KAM_DMARC_STATUS(0.01)


Thanks

You can either disable the rule by adding a custom rule score of 0 for it:
see 4.7.3 in https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_spamdetector

or you can configure your internal DNS server to not respond with the public dmarc record for your domain(s)

I hope this helps

Thanks for the fast reply.
My domains pass all dmarc test from different tester like mail-tester dot com. Why PMG add score to this ?

my first guess - your internal server which sends the mail to PMG is not in your SPF record because it's a private IP?

Ho yeah ! I forgot this.
Have a good day Stoiko !
