SPF records configuration

In order to configure SPF authentication for your e-mail communication, add the following SPF record to your domain: v=spf1 ~all.

You can have only one SPF record for your domain. If you already have an existing SPF record, you should modify it instead of creating a new one and add the entry For example, if your existing SPF record looks like v=spf1 ~all, the modified record should look like this: v=spf1 ~all.

DKIM records configuration

In order to configure SPF authentication for your e-mail communication, please follow the steps below:

1. Log in to your QuarticOn CDXP panel.

2. Go to the Settings tab.

3. Click on Advanced, navigate to the E-mail Deliverability section, and then select the option I will manage my own e-mail authentication.

4. Enter your sending domain in the DomainKeys Identified Mail (DKIM) field and click the Generate button.

5. We will generate a name and value for your TXT record.

Please note that the values generated here will not be saved on this page. These values will be needed to configure the TXT record in your DNS host.

Your DNS provider is usually the company where you registered your domain or the one that hosts your website. Most DNS hosts require the following elements to configure a TXT record:

  • Type: Choose TXT.

  • Name or host: Enter dk._domainkey (most common) or the full name of the TXT record displayed in QuarticOn. The choice depends on whether your DNS provider automatically appends the domain name to the DNS records created. If you're unsure which one to use, check the format of other DNS records in your settings (do they include the domain name in the Name or Host field?) or ask your DNS host.

  • Value or record: Enter the TXT record value displayed in QuarticOn.

  • TTL: This is the "time to live". Use the recommended or default setting of your DNS host. If there is no default setting, we recommend 3600 (one hour).

To find detailed instructions for your DNS host, use a search engine to search for Add TXT record in _____, replacing the blank with the name of your DNS provider.

6. After completing the configuration, you can test your e-mail live on the website mail‑ to verify that DKIM is working.

DMARC records configuration

To configure DMARC authentication, create a TXT record with the host or name _dmarc at your DNS provider, and enter the following value as the TXT record value. Remember to replace the e-mail address below with your own e-mail address:

v=DMARC1; p=none; pct=100;

If you don't replace the e-mail address in the above example with your own e-mail address, you won't receive DMARC reports. However, depending on the volume of sent e-mail messages, the e-mail inbox for the specified e-mail address may get overwhelmed. We highly recommend using a DMARC Monitoring solution, which can be configured to provide more organized and actionable results.
