PayPro sends emails on behalf of your webshop. Because these emails are sent from a different location than the emails you send from your own webshop, there is a chance that the emails sent by PayPro end up in your customer’s spam folder. DKIM ensures that outgoing emails are signed with a digital signature. This signature is verified via a public key in your DNS and helps prevent messages from being altered or marked as spam. For more information, see: http://dkim.org and https://dmarc.org.
A DKIM record is configured in the DNS settings of your web server. A DKIM record consists of three parts:
Selector: a unique name that refers to the correct DKIM key. For example: paypro
Subdomain: is standard always ._domainkey
Main domain: your own domain name, such as yourdomain.nl
Together, these parts form the DNS hostname of the record: paypro._domainkey.yourdomain.nl
At this address, you publish the public key in a TXT record so receiving mail servers can verify the signature of outgoing emails. Use the following values:
Selector: paypro
DKIM DNS value: MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAs/Wg9XfVGXd1EJmUerMTencdTYFQw1XZ4aNPtiVXqReRhZtLlYvLZIgDuZ/Ao8lltqF5Q5b5zfG/tkqXXYs1HRNVWxS6d5tq8HG+0D21ueMl0QUUM7nLWnLm8MvxtMXbbcDlD5A252qk4ysCVxIUUp5J6Pxs77p+xmdOzLnlzY+xfC7c3FmQf+MVH63eKuNyQT25B9zIZdVy36nLRWGDbnvWJ6LING0uq6dEgHxPlTvqgXFyqNXKt6gFRJ2vte0nHNQQS6pQey9eyTPg/5roETZT6AvFrWGlrPMKNpPLBSPhkjwFqbw6j0gcXlQGdLN4z7cqMXGReL77NDgOQjVcdQIDAQAB
