To prevent emails sent from the LDB from being classified as SPAM by the recipient, it is recommended to configure sender authentication using DKIM and SPF.

DomainKeys (DKIM) is an identification protocol to ensure the authenticity of email senders. It was designed to help curb unwanted email such as spam or phishing. Further help: what is a DKIM entry

The Sender Policy Framework (SPF) is a procedure designed to prevent the forging of an email's sender address. It originated as a method to combat spam. With SPF, the owner of a domain records in the Domain Name System which computers are authorized to send emails for that domain.

The settings for DKIM and SPF are stored as DNS TXT records for the email domain (e.g., labordatenbank.at). We are happy to assist you with entering the DKIM and SPF settings for your domain.
