SPF and DKIM are two terms that are frequently used in the context of email sending and spam.

Sender Policy Framework

To allow i-Reserve to send e-mails from the owner's domain, a so-called Sender Policy Framework (SPF for short) must be added to the (DNS records) domain settings at the customer's domain. This is the responsibility of the domain owner.

SPF is a protocol that aims to help reduce spam. It is hoped to reduce spam by determining whether the sender of an e-mail message is authorized to send a message. To set up SPF records, you can further inquire with the party where you purchased the domain or with the party that maintains the website (hosting).



DomainKeys Identified Mail

DomainKeys Identified Mail (DKIM) is a technique for providing e-mails with a cryptographic signature. This signature is invisible to a normal recipient. Receiving mail servers check a message by comparing the signature with the sender's settings. Isn't it right? Then the mail will be marked as invalid. Based on this, a spam filter can decide to block the e-mail or treat it as possible spam.

With DKIM you know that an e-mail really comes from that sender. You can then vouch for the authenticity of a message sent on behalf of your organisation.
