Problem with DKIM, SPF and Dmarc

[tasior22]

Hello, do you have any reliable websites or tools for generating DKIM, SPF, and DMARC records? Some servers treat my Hestie-generated messages as spam, and I get responses like the one in the image.

I am sending the domain settings

In Cloudflare, you added the DKIM info to the wrong place. You added it to your base domain webdesign-studio.com.pl but you must add it to mail._domainkey.webdesign-studio.com.pl subdomain record.

DMARC and SPF is correctly added.

[tasior22]

Could you show me how to add it correctly so I don’t make a mistake?

[sahsanu]

In Name field remove the base domain and add mail._domainkey

[tasior22]

@sahsanu

mail._domainkey

will it be okay?

[sahsanu]

Yes, seems so.

[tasior22]

Thanks for your help. I think my email will be working normally now. Now I have to wait 24 hours?

@tasior22

Thanks for your help.

You’re welcome.

@tasior22

Now I have to wait 24 hours?

No, it should work now.

However, after sending the email I received this reply:

[sahsanu]

You should create a PTR record for your current public IP that resolves to the same hostname your mail server uses to identify itself, in this case webdesign-studio.com.pl.

Note: The PTR record must be created on your hosting side, not Cloudflare.

You can also test your mail server using this site:

Newsletters spam test by mail-tester.com

[tasior22]

so this ptr record would have to be added by the hosting provider, right

[sahsanu]

Yes, but usually you should be able to change it through the control panel provided by your hosting company.

[tasior22]

Unfortunately, I can’t because they also added revdns to me, I don’t have that option.

[sahsanu]

@tasior22

I can’t because they also added revdns to me

Sorry, I don’t understand what you mean.

[tasior22]

I wanted to write that my hosting provider did not provide these options in the panel, such as adding prt and revdns records, I just have to write a ticket and they will add it.

Hello, me and my friends who use Hestia mail with me still get this reply after sending a message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

recipients. This is a permanent error. The following address(es) failed:

[email protected]

host mail.nsm.org.pl \[195.78.66.221\]

SMTP error from remote mail server after end of data:

550-Your message to <[[email protected]](mailto:[email protected] "mailto:[email protected]")> was classified as SPAM.  Please add

550-more content, cut down on HTML links, use fewer naughty words etc.  Also,

550-ask your IT dept to make sure your mailserver has REVERSEDNS, SPF, DKIM,

550 and is not on any black lists. Your score:

170

can i fix it somehow revdns and prt records added.

[sahsanu]

The second command should return webdesign-studio.com.pl but it returns nothing.

❯ dig webdesign-studio.com.pl +short
83.168.108.58
❯ dig -x 83.168.108.58 +short

Example of an IP with a PTR configured:

❯ dig mail.hestiacp.com +short
116.203.78.202
❯ dig -x 116.203.78.202 +short
web02.hestiacp.com.

Your hosting provider didn’t add the PTR record for your IP. You should contact them about this.
