DKIM Key

Introduction

In order for ESco to send emails on behalf of a client domain, a valid DomainKeys Identified Mail (DKIM) key needs to be in place. DKIM allows the recipient’s mail server to know that the message was sent and authorised by the owner of the domain.

By adding a DKIM key to your domain, you will authorise emails to be sent from the ESco mail servers on behalf of your domain.

Alongside a valid SPF record, adding a DKIM record increases the deliverability of emails sent on your behalf.

More information on DKIM keys and adding a DKIM record lookup can be found here.

DKIM Key Requirements

ESco is unable to support domain administration tasks for third party domains and therefore require that DKIM key addition or amendments should be handled by your domain administrator.

ESco will provide the records to add to the DNS, including the below example fields:

Host:

msgf._domainkey.yourdomain.co.uk

Data:

( "v=DKIM1; k=rsa; p=EXAMPLEKEY" )

This facilitates the following:

• Bulk email campaigns including but not limited to welcome and renewal communication
• Customer Service communication
• Communication from hosted web services including but not limited to order confirmation and password resets

An example DomainKey record, which defines your public DKIM key, should look like the below:

msgf._domainkey.yourdomain.co.uk. IN TXT "v=DKIM1; k=rsa; p=EXAMPLEKEY"
