E-Mail Communication

In order for emails to be sent under your domain by the DeDeNet systems, it is necessary to set an SPF record with your DNS provider.
Include our entry spf.dedenet.de in your SPF record using the Include directive.
If you use Microsoft 365, this could look as follows:
v=spf1 include:spf.protection.outlook.com include:spf.dedenet.de -all
