Issue DMARC control fails

Hi all,

We have problems with some domains and DMARC.
Some emails are not received.

In the logs, there are lines like this:

DMARC: smtpdomain=em9713.email.wetransfer.com maildomain=wetransfer.com mailfrom=noreply@wetransfer.com stamp=1685452387 ip=185.209.208.10 adkim=relaxed aspf=relaxed p=REJECT sp=UNSPECIFIED pct=100 align_dkim=fail align_spf=fail spfres=fail dkimres=unknown dmarccheck=DMARC_POLICY_REJECT dmarcstatus=STOP
postfix-local[2662592]: 062FD1C1CC31E: dmarc: stderr: STOP

For example, mails from Wetransfer (known service legitim) are no received.

An idea of the problem?
If not, is it possible to exclude some custormers/domains from the DMARC control on a server?

Hi @Erwan, thank you for asking. Here is KB article that could help:

Hi Peter,
I had found this but unless I am mistaken, it is used to indicate senders to authorize (here noreply@wetransfer.com).

Is there a way to exclude the recipient domain (our client installed in Plesk)?

 

[Peter Debik]

I don't think that disabling DMARC checking for a specific recipient domain is supported.

Peter's right. Either DMARC checks are disabled server-wide, or individual domains are whitelisted from the check with the article he shared.
