What are the MX DNS records?
If your domain is to use the hosting.fr mail servers, corresponding MX records must be configured in your domain’s DNS zone.
The “MX” type records necessary for mail functionality are as follows:
mx01.routing.net (Priority 10), mx02.routing.net (Priority 10), mx03.routing.net (Priority 10), mxbackup.routing.de (Priority 20)
You create the records in the DNS zone as follows:
- Select the “Products” item in the menu on the left.
- In the “Products” menu, select the “DNS” sub-item.
- Under the DNS zone to be modified, select “Show details”. If you manage a larger number of domains, you may need to click “Show all” beforehand to get a complete overview of your DNS zones.

- In the “Records” section, select the “Edit” option.

With the “+” button, you can create a new record. It should be composed as follows:
- The “Record name” field generally remains empty. You only need to fill this field if you are using a subdomain such as “shop.mustermann-domain.de” and want to create email addresses for this subdomain. In this specific example, you would enter “shop” in the “Record name” field.
- Choose “MX” in the “Record type” field.
- In the “Target” field, enter the target record, for example, “mx01.routing.net”.
- In the “Priority” field, indicate the priority of the record.
- In the “TTL” field, indicate the period during which new records are updated on the name servers. This time is measured in seconds. Please indicate a TTL of at least 3,600 = 1 hour. The longer the update period, the lower the server load.
- You confirm each record via the checkmark icon on the right.
- Once you have created all the records, validate all changes with the “Save” button.

If you want to use the SPF security mechanism, please create a corresponding record in your domain’s DNS settings in the “TXT” format with the following content:
"v=spf1 include:spf.routing.net -all"
You will find a complete overview of the SPF record syntax at SPF Record Syntax.
