Guide de configuration des protocoles de messagerie Red Sift

In this chapter, we provide guidance on how to create TXT records, as well as specific DNS setup instructions for some of the most popular ESPs - from Mailbox Providers (MBPs) like Gmail and Microsoft to Shopify and Squarespace, through to CRMs such as Salesforce and Hubspot.

1. Log in to your Route 53 Console.
2. In the navigation pane, choose 'Hosted zones'.
3. Choose the domain that you want to add a TXT or CNAME record to.
4. Choose 'Create record'.
5. For 'Routing policy, choose Simple routing, and then choose Next.
6. Choose Define simple record.
7. In the Define simple record pane, do the following:
8. - For Record name, Enter the host name for the TXT record. For example, leave this blank for an SPF record, or enter the value _dmarc for a DMARC record.
9. - For Value/Route traffic to, paste the value you are setting as the destination of the Host or the text value of the TXT.
10. - For Record type, choose TXT or CNAME as appropriate.
11. - For TTL (seconds), type 1800.
12. - Choose Define simple record.​
13. Allow up to 24 hours for propagation of the newly created record.​

Increase the deliverability of your Brevo (formerly Sendinblue) emails by correctly configuring SPF and DKIM.

Adding SPF for Brevo (formerly Sendinblue) for DMARC purposes is not needed because the Return-Path address of the emails is set to their default domain in order to track bounces on your behalf. Therefore, SPF will not pass for Brevo from a DMARC perspective, however, as long as DKIM passes, the emails will be DMARC compliant.

To enable DKIM you will have to create a few DNS records. Please follow the instructions using the button below for more information.

To authorize Google to send emails on your behalf you will need to create an SPF record that includes the following value:

include:_spf.google.com <-- this part allows all Gsuite IPs to send emails on your behalf.

If you already have an existing SPF record you will just have to copy the include include:_spf.google.com and append it to your current SPF record, however, it has to be put after the v=spf1 and before the ~all ending mechanism in your record.

If you already have an existing SPF record such as:

v=spf1 include:mail.zendesk.com ~all

and you would like to add Gsuite as an additional sending service, you will have to copy the include include:_spf.google.com and append it to your current SPF record. 

The final SPF record should look like this:

v=spf1 include:mail.zendesk.com include:_spf.google.com ~all

Do not create a second SPF record if you already have one. You should only have one SPF record per domain/subdomain.

To learn more about SPF and how to configure it for Google Workspace please click here.

To implement DKIM for your domain you will have to follow the steps below.

1. Log in as administrator and go to the Admin Console.
2. Go to Apps --> G Suite
3. Click on the Gmail app.
4. Click on Authenticate email
5. For the key length you can choose between 1024 or 2048. The longer the key the better, however, some DNS providers do not support keys longer than 1024. They should be able to implement 2048 as well but there may be some additional work that needs to be carried out.
6. Select your prefix selector, you can leave the default of "google" or type in your own. This will be your DKIM selector.
7. Once the key is generated, you will need to take the information provided and put it in your DNS ie. create the TXT record. It will look like the example below, except that you will have to replace the word "selector" below with the one that you created earlier.

Adding SPF for Hubspot for DMARC purposes is not needed because the Return-Path address of the emails is set to Hubspot's default domain in order to track bounces on your behalf. Therefore, SPF will not pass for Hubspot from a DMARC's perspective, however, as long as DKIM passes, the emails will be DMARC compliant.

Mailerlite provides two ways of authenticating your domain. They can either manage the authentication for you or allow you to manage it yourself. If you let Mailerlite authenticate your emails then your receivers would see Mailerlite as the sender of your emails. If you would like your receivers to see your domain only then you will have to choose the option to authenticate emails yourself. 

Configuring SPF and DKIM with Mailerlite for your custom domain is pretty easy. All you have to do is choose Authentication, insert your domain and select Show DNS record.

The necessary SPF and DKIM records will be generated and presented to you which you will then have to add to your DNS. For more information please click here.

Once you have created SPF and DKIM but still showing as inactive in your account, please click here for information on how to troubleshoot this.

Mandrill is a product created by Mailchimp and is a service used to send transactional emails. To improve your email deliverability, Mandrill requires that every domain of yours is configured with SPF and DKIM.

To allow Mandrill to send emails on your domain’s behalf, you must include them as part of your SPF record. 

The SPF mechanism used by Mandrill is the following:

include:spf.mandrillapp.com

Mandrill uses their own domain as part of the Return-Path address (used by SPF) and hence SPF alignment would not occur. However, this can be modified as per their help article.

For more information, visit the Mandrill help article.

To set up DKIM for Mandrill, you will need to add a new TXT record in your DNS.

The name for the TXT record should be: 

mandrill._domainkey.yourdomain.comReplace “yourdomain.com” above with the domain you are setting up.

The value of the DNS record should be the following:

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;

After you have added the required DNS records, you can use the Test the DNS Settings button in your control panel to make sure that everything that you have added has a green checkmark. Please allow 24-48 hrs for the DNS changes to take effect. 

For more information, visit the Mandrill help article.

To authorize Microsoft Dynamics 365 to send emails on your behalf, you must include it in your SPF record. The SPF record mechanism used for Microsoft Dynamics 365 is shown below. Find more information here.

include:marketing.dynamics.com

Microsoft Dynamics 365 supports DKIM signing for your custom domain. For more information on how to set it up please click on the button below. Find more information here.

To authorize Microsoft 365 (formerly Office 365) to send emails on behalf of your domain you will have to add it to your SPF record. The SPF record mechanism used for Microsoft 365 is: 

include:spf.protection.outlook.com <-- this part allows all Office 365 IPs to send emails on your behalf.

If Microsoft 365 is your only legitimate source of emails, your SPF record should look like the below example:

v=spf1 include:spf.protection.outlook.com ~all

If you already have an existing SPF record such as:

v=spf1 include:mail.zendesk.com ~all

and you would like to add Office 365 as an additional sending service, you will have to copy the include include:spf.protection.outlook.com and append it to your current SPF record. The final SPF record should look like this:

v=spf1 include:mail.zendesk.com include:spf.protection.outlook.com ~all

However, do not create a second SPF record if you already have one. You should only have one SPF record per domain/subdomain.

If you are using Dynamic SPF and you also use Microsoft 365 for email, you may have noticed that Microsoft will give you a warning about your SPF include being incorrect.

This is expected and you can safely ignore it. Microsoft is looking for the literal string they provide in your DNS and does not know that their IP ranges are already included in Dynamic SPF.

You can test Dynamic SPF is working correctly by sending a test email to the address listed in the Investigate section of the OnDMARC console.

In order to DKIM sign your custom domain emails you will need to complete the following steps.

The CNAME records are used to map an alias name to the true or canonical domain name. In essence, when you provision a new domain name in Microsoft 365 you will need to create two CNAME records for it so that it points to your initial domain. 

We will use example.onmicrosoft.com as our initial domain, also called the tenant domain. But we actually own example.com and after we provision it in Office 365 we need to publish the two CNAME records so that example.com points to example.onmicrosoft.com using the format below.

Please note that if you are a Microsoft 365 US Government Cloud (GCC) customer, the domainGUID method below will not work for you. You will need to use the proper MX value for your domain. Example: 

selector1-<domain-key>._domainkey.<initialDomain> 

Use this article to find the MX record needed for your domain-key value.

Host name: selector1._domainkey.<domain>
Points to address or value: selector1-<domainGUID>._domainkey.<initialDomain>
TTL: 3600

Host name: selector2._domainkey.<domain>
Points to address or value: selector2-<domainGUID>._domainkey.<initialDomain>
TTL: 3600

In our example the CNAME records will look like this:

Host name: selector1._domainkey.example.com
Points to address or value: selector1-example-com._domainkey.example.onmicrosoft.com
TTL: 3600

Host name: selector2._domainkey.example.com
Points to address or value: selector2-example-com._domainkey.example.onmicrosoft.com
TTL: 3600

Please pay close attention to the domainGUID which does not use a full stop "." but a dash "-" instead. This is taken from the MX record of your custom domain, in this case, example.com.example.com.

The reason behind the two CNAME records is that Microsoft rotates the two keys for added security.

Once you have added the CNAME records (two per domain) DKIM signing can be enabled through the Microsoft 365 Security admin center at http://security.microsoft.com/dkimv2
