To ensure that your e-mail address appears as the sender when Komfortkasse sends e-mails on your behalf, you'll need to configure a few DNS settings.

Why?
This is necessary to ensure that the e-mails are not classified as spam.

What happens if you don’t?
If you do not configure these settings, an e-mail address from Komfortkasse will be used as the sender address. Your e-mail address will be included as the “Reply-To” address. If a customer replies to such an e-mail, the reply will automatically be sent to the “Reply-To” address. Note: Some email programs or apps do not support this feature.

Quick Guide

Add the following CNAME record for DKIM (replace {DOMAIN} with the domain of the e-mail address):
Komfortkasse._domainkey.{DOMAIN} CNAME dkim.komfortkasse.eu.
Add the following TXT record for SPF:
v=spf1 include:spf.komfortkasse.eu ~all If
you are already using SPF, add include:spf.komfortkasse.eu to your existing SPF record.

Detailed Instructions

Note: You need access to the domain specified for the e-mail address you’re using. So, if your shop is accessible at www.mein-shop.de, the e-mail address must end in @my-shop.de (or another domain to which you have access). You cannot use a general e-mail address such as Gmail, Hotmail, or one from your internet service provider, since you do not have access to the DNS settings for those domains.

To specify the settings, you need access to the DNS settings. You usually receive this access from your web hosting provider.

One record is required for DKIM and one for SPF.

DKIM entry

Create a new CNAME record:

  • Type: CNAME
  • Name: Komfortkasse._domainkey
  • Value: dkim.komfortkasse.eu. (If you have received an Error message, try dkim.komfortkasse.eu)
  • TTL (time-to-live): 3600 (1 hour)
  • Priority: Empty or set to 1

Examples:

If your provider does not allow a CNAME record (e.g., 1&1), you can alternatively add an TXT entry:

  • Type: TXT
  • Name: Komfortkasse._domainkey
  • Content: v=DKIM1;g=*;k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCmHrnduDqx+yZqhw7NdJEPWDBphl3/+Aj6cPQVzM5I8A/nJtipRDSNF0kxrXrp9UaGHk8Uw+0/MK3LWCil4bkXokeOJY//92xdiOG1CSR/bGwgpTU2leRy2BIWLqt/Ji5ft5RZI3xLQYQfIMGDAmVtul3wyJyDcdwbco8eomwm6wIDAQAB;s=email;t=s
  • TTL (time-to-live): 3600 (1 hour)
  • Priority: empty or set to 1

SPF record

First, validate whether an SPF record already exists. Search for an existing TXT record of type v=spf1. Example:
Depending on whether such a record already exists, it must be changed or a new entry must be added.

SPF record already exists

Change the existing record. The record is formatted similarly to v=spf1 include:provider.de -all or v=spf1 a:provider.de ip4:1.2.3.4 ~all and usually ends with the word all after characters such as - or ~.

Insert ` include:spf.komfortkasse.eu ` immediately before the end, for example:
v=spf1 include:provider.de include:spf.komfortkasse.eu -all or
v=spf1 a:provider.de ip4:1.2.3.4 include:spf.komfortkasse.eu ~all.

Warning! Do not change or delete the existing text. This can cause disruptions in your e-mail system.

SPF record does not yet exist

Add a new entry of type TXT:
  • Type: TXT (Text)
  • Name/Hostname/Subdomain: empty
  • Content: v=spf1 include:spf.komfortkasse.eu ~all
  • TTL (time-to-live): 3600 (1 hour)
  • Priority: Leave empty or set to 1

Examples:

Entry for DMARC

If the SPF and DKIM records are active, you can create a DMARC record for your domain. The DMARC record specifies that e-mails from your domain are protected by SPF and DKIM, and how to handle e-mails that are not SPF- and DKIM-compliant. No specific settings are required for Komfortkasse for the DMARC record.

Example of a DMARC record:

v=DMARC1;p=none;pct=100

Important: If you use a DMARC record, you must ensure that all e-mails sent from your domain (not just those sent via Komfortkasse) are SPF- and DKIM-compliant! Otherwise, e-mails from your online shop, for example, may no longer be delivered.

That’s it!

Now you just need to wait for the DNS setting to take effect. This usually takes one hour due to the specified TTL setting, but in exceptional cases it can take up to one day.
Once the setting is successfully recognized, you’ll be notified by e-mail. You can also check the current status at any time in the Komfortkasse merchant area under Shops -> Email Settings -> DNS settings.
