Domain Keys Identified Mail (DKIM) helps you protect your company fromemail spamming and phishing attempts. It provides a method forvalidating a domain name identity that is associated with a messagethrough cryptographic authentication.

DKIM stands for DomainKeys Identified Mail and is an authentication method that helps ensure the sender's email address is legitimate and not being spoofed by a third party.

  2. Generate a public-private key pair.

  3. Publish the selector and public key by creating a DKIM TXT record.

  4. Attach the token to each outgoing email.

What is a DKIM selector?

A selector is specified as an attribute for a DKIM signature and is recorded in the DKIM-Signature header field.

Because DKIM selectors give different DNS query names, the system uses the selector as an additional name component for validation. Under each domain name, there might be one too many unique DKIM DNS records associated with different selectors.

Selectors enable multiple keys under a domain name, which can provide separate signatory controls among departments, date ranges, or third parties acting on behalf of the domain name owner. No two services or products should use the same selector.

A selector can be anything you want, such as a word, number, or a string of letters and numbers.

For example, if you choose oct2019 for your selector, the domain name wouldbecome oct2019._domain.example.com.

Before you begin

Before you log in to the control panel and create a DKIM record, there area couple of things that you need:

  1. Choose a simple, user-defined text string to be your DKIM selector. Theselector is appended to the domain name to help identify the DKIM publickey. See the previous section for more information about choosing aDKIM selector.

  2. Generate a public-private key pair by using a tool such as ssh-keygen onLinux or PuTTYgen on Windows. For help creating key pairs, seeGenerate RSA keys with SSH by using PuTTYgen.

Create a DKIM TXT record

Use the following steps to create a DKIM TXT record in the Cloud ControlPanel:

  1. Log in to the Cloud Control Panel.

  2. In the top navigation bar, click Select a Product > Rackspace Cloud.

  3. Select Networking > Cloud DNS.

  4. Click the gear icon next to the name of an existing domain andselect Add DNS Record.

  5. In the pop-up dialog box, select TXT Record as the record type.

  6. In the Hostname text box, enter the selector text string that you chosein Step 1, followed by the literal string ._domainkey. For example, if youuse the default as the text string, you enter default._domainkey in theHostname text box.

  7. Expand the Text box by dragging the corner, and then enter thefollowing information, pasting the public key that you generated in theprevious section after the p= prompt:

    When you finish, the TXT record looks similar to the followingexample:

  8. Click Add Record.

The DKIM TXT record is added to your domain.

For instructions about attaching the token to your outgoing email, see theSpecification section at DKIMcore.org.

Introduction

This document describes how to configure DKIM signing on an ESA.

Requirements

  1. Access to the Email Security Appliance (ESA).
  2. Access to DNS to add/remove TXT records.

Dkim Key Format

Ensure that DKIM signing is off

Before we make any changes, we want to ensure that DKIM signing is off in all mail flow policies. This will allow us to configure DKIM signing without any impact to mail flow:

  1. Go to Mail Policies > Mail Flow Policies.
  2. Go to each mail flow policy and ensure that 'Domain Key/DKIM Signing' is set to 'Off.'

Create a DKIM signing key

You will first need to create a new DKIM signing key on the ESA:

Generate The Dkim Domain Key To Computer

  1. Go to Mail Policies > Signing Keys and select 'Add Key..'
  2. Name the DKIM key and either generate a new private key or paste in an existing one.

    Note: In most cases, it's recommended that you choose a 2048 bits private key size. Generate aes key from password c.

  3. Commit the changes.

Generate a new DKIM signing profile and publish the DNS record to DNS

Next, you will need to create a new DKIM signing profile, generate a DKIM DNS record from that DKIM signing profile and publish that record to DNS:

  1. Go to Mail Policies > Signing Profiles and click 'Add Profile..'
    1. Give the profile a descriptive name in the field 'Profile Name.'
    2. Enter your domain in the field 'Domain Name.'
    3. Enter a new selector string into the field 'Selector.'

      Note: The selector is an arbitrary string that is used to allow multiple DKIM DNS records for a given domain.

    4. Select the DKIM signing key created in the previous section in the field 'Signing Key.'
    5. Click Submit.
  2. From here, click 'Generate' in the column 'DNS Text Record' for the signing profile you just created and copy the DNS record that is generated. It should look similar to the following:
  3. Commit the changes.
  4. Submit the DKIM DNS TXT record in step 2 to DNS.
  5. Wait until the DKIM DNS TXT record has been fully propagated.
  6. Go to Mail Policies > Signing Profiles.
  7. Under the column 'Test Profile', click 'Test' for the new DKIM signing profile. If the test is successful, continue with this guide. If not, confirm that the DKIM DNS TXT record has been fully propagated.

Turn DKIM signing on

Now that the ESA is configured to DKIM sign messages, we can turn DKIM signing on:

Dkim Wizard

  1. Go to Mail Policies > Mail Flow Policies.
  2. Go to each mail flow policy that has the 'Connection Behavior' of 'Relay' and turn 'Domain Key/DKIM Signing' to 'On.'

    Note: By default, the only mail flow policy with a 'Connection Behavior' of 'Relay' is the mail flow policy called 'Relayed.' The important thing to remember here is that we only want to DKIM sign messages that are outgoing.

  3. Commit the changes.

At this point, you are done with configuring DKIM any further. However, you should test DKIM signing to ensure that it's signing your outbound messages as expected and passing DKIM verification:

  1. Send a message through the ESA ensuring that it gets DKIM signed by the ESA and DKIM verified by another host.
  2. Once the message is received on the other end, check the headers of the message for the header 'Authentication-Results.' Look for the DKIM section of the header to confirm if it passed DKIM verification or not. The header should look similar to the following:
  3. Look for the header 'DKIM-Signature' and confirm that the correct selector and domain are being used:
