Dkim dmarc

Friends. I’m having difficulties configuring the DKIM and DMARC of the ava.souenfermagem.com.br subdomain

Can you help me?

The main domain https://souenfermagem.com.br is correctly configured for DKIM and DMARC.

The subdomain is wrong https://ava.souenfermagem.com.br .

I’ve already contacted Google 2 days ago and put the DKIM through the admin panel.

DOMINION PRINCIPAL:
https://toolbox.googleapps.com/apps/checkmx/check?domain=souenfermagem.com.br&dkim_selector=

SUBDOMINIO:
https://toolbox.googleapps.com/apps/checkmx/check?domain=ava.souenfermagem.com.br&dkim_selector=

What can I do?

Appreciate.

Are you actually using email addresses from @ava.souenfermagem.com.br ?

If so, can you please post a screenshot of your DKIM and DMARC record from the Cloudflare DNS page?

You should have TXT record for _dmarc.ava
As for the DKIM record, that’s determined by your mail host, so I’m not sure what that should look like for you.

I find that dmarcian.com does a pretty good job of verifying records, and mail-tester.com is good for testing an actual email sent out.

Thakns your.
yes. actually using email addresses from `@ava.souenfermagem.com.br.


Cloudflare is publishing that TXT record as entered. Personally, I think it’s backwards (ava._domainkey), but I’ve not tried DKIM on a subdomain.

It doesn’t look like you have a _dmarc record for the subdomain.

These are questions for a mail admin forum, as Cloudflare DNS is doing exactly what you’re telling it to do.

The DKIM hostname format is:

<DKIMSelector>._domainkey.<FQDN>

Usually Google Workspace uses google as the DKIM Selector.
The FQDN in this case, is the part after the @ in the email address.

So, in your case both the selector and the subdomain seems to be ava, as per this screenshot:

So, on cloudflare, Nome would be:
ava._domainkey.ava
