In order for your e-mail address to be specified as the sender when Komfortkasse sends e-mails in your name, you must make some DNS settings.

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

What if not?
If you do not make the 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 is automatically sent to the "Reply-To" address. Note: some mail programs or apps do not support this function.

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 ~allIf
you are already using SPF, add include:spf.komfortkasse.eu to your existing SPF record.

Detailed instructions

Note: You need access to the domain of the specified E-mail address. So if your shop can be reached at www.mein-shop.de, the e-mail address must end in @mein-shop.de (or another domain that you have access to). You cannot use a general e-mail address such as Gmail, Hotmail or that of your Internet provider, as you do not have access to the DNS settings of these domains.

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

An entry for DKIM and an entry for SPF are required.

Entry for DKIM

Create a new CNAME entry:

  • Type: CNAME
  • Your name: komfortkasse._domainkey
  • Content: dkim.komfortkasse.eu. (if you receive an Error message: try dkim.komfortkasse.eu)
  • TTL (time-to-live): 3600 (1 hours)
  • Priority: leave empty or 1

Examples:

If your provider does not allow a CNAME entry (e.g. 1&1), you can alternatively add a 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 hours)
  • Priority: leave empty or 1

Entry for SPF

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

SPF entry already exists

Change to the existing entry. The entry has a form similar 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 a character such as - or ~.

Insert include:spf.komfortkasse.eu directly before the end, e.g.
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.

Attention! Do not change or delete the existing text. This can lead to malfunctions in your e-mail system.

SPF entry does not yet exist

Add a new entry of the type TXT:
  • Type: TXT (text)
  • Your name/hostname/subdomain: empty
  • Content: v=spf1 include:spf.komfortkasse.eu ~all
  • TTL (time-to-live): 3600 (1 hours)
  • Priority: leave empty or 1

Examples:

Entry for DMARC

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

Example of a DMARC entry:

v=DMARC1;p=none;pct=100

Attention: if a DMARC entry is used, it must be ensured that all e-mails sent from your domain (not only by Komfortkasse) are SPF and DKIM compliant! Otherwise, e-mails from your online shop, for example, could no longer be delivered.

That's it!

Now you have to wait for the DNS settings to take effect. This normally takes one hour due to the specified TTL setting, but can take up to days in exceptional cases.
If the setting is recognized successfully, you will be informed by e-mail. You can also view the current status at any time in the Komfortkasse merchant area under Shops -> E-mail settings -> DNS settings.
