SPF record at the mail provider

What is an SPF record?

SPF (stands for Sender Policy Framework, i.e. “safe sender”) record in your domain, must be stored as an entry in your domain, i.e. your website. It basically serves to protect against SPAM. It is important to understand here that the SPF record ensures that your mails are not classified as SPAM by the recipient server. If you store the SPF entry, you ensure that the recipient server can check your mail whether you, as the sender, are SPAM or not. The mail header is checked to see whether the sender domain also matches the sender server.

Easily explained:
If you store the SPF record and write an email, the SPF record tells the recipient: "Hello, I'm not spam."


How can I add this record?

A TXT record with the following content must be created in the DNS settings of your mail provider:
„v=spf1 ip4: include:_spf-eu.ionos.com ~all“
The picture shows this using the example of 1&1/Ionos. With other providers, the interface may look slightly different.

For the procedure with the provider ALL-INKL. You can find instructions for the SPF entry here: Instructions ALL-INCL. SPF record

Mail providers are gradually tightening their spam rules. We have noticed this again and again with countless providers over the past few years. Unfortunately, the rules are constantly changing and you have to "retrofit".
