2024 Comprehensive Guide to DMARC, SPF, DKIM, and the Greenbackend Advantage
Comprehensive Guide to DMARC, SPF, DKIM, and the Greenbackend Advantage
In today’s interconnected world, email communication serves as a linchpin in both personal and professional domains. The imperative to ensure the security and authenticity of email messages has never been more critical. This article delves into three pivotal protocols—DMARC, SPF, and DKIM—that play instrumental roles in mitigating the risks associated with phishing and unauthorized email activities. Additionally, we introduce Greenbackend, an email service provider that not only aligns with these stringent standards but also garners high recommendations from industry titans such as Google and Yahoo.
1. Deciphering Email Authentication Protocols: DMARC, SPF, and DKIM
DMARC (Domain-based Message Authentication, Reporting, and Conformance):
DMARC stands as a robust and comprehensive email authentication protocol designed to combat the escalating threats of email phishing and fraud. It operates synergistically with SPF and DKIM, empowering domain owners to precisely delineate the authentication process for their emails and prescribe actions for unauthenticated messages.
SPF (Sender Policy Framework):
SPF provides a mechanism for domain owners to assertively define which mail servers are authorized to dispatch emails on their domain’s behalf. By disseminating SPF records through the Domain Name System (DNS), organizations can significantly diminish the risks of email spoofing, ensuring that only legitimate servers are sanctioned to transmit emails under their domain.
DKIM (DomainKeys Identified Mail):
Incorporating an additional layer of security, DKIM digitally signs outgoing emails. The recipient’s email server then performs a verification process on the signature, thereby affirming the message’s authenticity and guaranteeing that it remains unaltered during its transit.
2. Greenbackend: An Unparalleled Blend of Security and Sustainability

The Strategic Integration of DMARC, SPF, and DKIM
As we navigate the complex terrain of email security, the strategic integration of DMARC, SPF, and DKIM emerges as a formidable defense against the proliferating threats of phishing and unauthorized access. DMARC, in its role as a comprehensive framework, synergizes the efforts of SPF and DKIM, providing a unified front to safeguard against fraudulent email activities. Organizations that adopt and implement these protocols not only fortify their defenses but also foster a climate of trust and reliability in their email communications.

Three key protocols—DMARC, SPF, and DKIM—play crucial roles in mitigating the risks associated with phishing and unauthorized email activity. In this article, we’ll explore these protocols and introduce Greenbackend as an email service provider that not only supports these standards but also comes highly recommended by industry giants Google and Yahoo.
1. Understanding Email Authentication Protocols: DMARC, SPF, and DKIM
DMARC (Domain-based Message Authentication, Reporting, and Conformance):
DMARC is a comprehensive email authentication protocol that helps organizations combat email phishing and fraud. It leverages both SPF and DKIM, providing a mechanism for domain owners to specify how their emails should be authenticated and what actions should be taken for unauthenticated messages.
SPF (Sender Policy Framework):
SPF allows domain owners to define which mail servers are authorized to send emails on behalf of their domain. By publishing SPF records in DNS, organizations can reduce the likelihood of email spoofing and ensure that only legitimate servers send emails using their domain.
DKIM (DomainKeys Identified Mail):
DKIM adds an extra layer of security by digitally signing outgoing emails. The recipient’s email server can verify the signature, confirming the authenticity of the message and ensuring it hasn’t been tampered with during transit.

How to add DKIM records manually
Firstly, access the DNS Management interface for your domain name. If the domain is registered with us, you can access this from the Manage Domains area of the control panel, select the domain from the action sidebar and choose (login to domain).
- Ensure you’ve selected the domain you want to add the DKIM record-to.
- Add a Selector (e.g gbeselector). This can be any value or name you like. It’s simply a field to identify the DKIM record. Then select Add Signature.
The signature will be added immediately to emails sent from the mailboxes under the domain selected. We will have automatically added a DNS record to Manage DNS. You may wish to wait for this to resolve for DKIM to be effective.
From here you’re all done: your emails will use DKIM as a method to authenticate email.
- If your nameservers are with greenbackend, we’ll automatically add the correct TXT record for you.
You can also use the Advanced Options section.
ℹ️ Note: This is only recommended if you’re familiar with customizing DKIM signatures. Below is a description of each section and how it alters the DKIM signature that’s added to the header of emails sent.
Selector – This is a unique identifier for the DKIM record and can be set to any value you like. For example you could set it to indicate the name of an office location or the signing date (e.g. “october2023”).
Granularity/Identity – By default this is set to a wildcard value: ‘*’. You can use this field to set the DKIM record to be assigned to a specific mailbox, allowing you to constrain which mailbox can use this selector legitimately. For example, if you set the value of this field to be ‘sales’, only your sales@domain.com mailbox will use this DKIM signature. This field must match the local part of the signing address (mailbox).
Note – This field does not form part of the DKIM record or signature and is simply there so you can record any information about this record for your own information.
Service Type – Currently, DKIM only supports signatures added to messages sent via ‘Email’ (i.e. SMTP). However, in the future the DKIM standard may add more service types such as IM or VoIP, which we’ll then be able to support. This field can be left to either ‘*’ or ‘Email’ – changing this won’t influence behaviour at present.
Canonicalization – Some mail servers and relay systems may modify an email in transit, potentially invalidating a DKIM signature. There are two options you can set: ‘Simple’ and ‘Relaxed’. If you expect your email to be modified in any way, you should select Relaxed which is more forgiving to changes made the header and body of the email.
Expiry Time – This is the time which, when elapsed, the DKIM signature will be invalidated in the mail header. By default it’s set to 86400 seconds (1 day). You may wish to extend this if you believe deliverability of the email will take longer than 1 day.
Flags – There are two flags available: ‘Production’ and ‘Testing’. If you select Testing, you’ll still receive a response to the email and the DKIM signature from the remote mail server, but the email won’t be treated with different behaviour. Verifier systems may wish to track testing mode results to assist the signer. You’ll mostly want to use Production.
How to add SPF records manually
Firstly, access the DNS Management interface for your domain name. If the domain is registered with us, you can access this from the Manage Domains area of the control panel, select the domain from the action sidebar and choose (login to domain).
If the domain is not with us but is assigned to a hosting package, you can reach this interface via the Manage Hosting -> Select Package -> Manage DNS section.
Towards the bottom of the Manage DNS page, you will see 3 inputs to allow you to add new records. To add it:
- Leave the Name field blank
- Select TXT for Type
- Enter v=spf1 include:spf.stackmail.com a mx -all as data
Then save the changes. Your domain is now protected by an SPF record.
What is SPF?
Sender Policy Framework (SPF) records help reduce the chance of your domain being spoofed in spam messages. It can also increase the deliverability of e-mail to external providers such as Gmail and Outlook.
We maintain an SPF record that is kept up to date with all IP addresses used to transmit email from our network. This ensures that any email sent from our services passes an SPF check. To use this on your domain, you need to add a TXT record in DNS.
How to add DMARC records manually
Firstly, access the DNS Management interface for your domain name. If the domain is registered with us, you can access this from the Manage Domains area of the control panel, select the domain from the action sidebar and choose (login to domain).
- Log in to your cp.greenbackend.com account and go to Manage Hosting > Options > Manage.
- Click on DMARC Wizard under Email.
- Choose your domain name in the Domain field.
- Choose the requested policy type from the drop-down menu. The recommended option is None if you are unsure. This means that you only want to monitor the DMARC reports and not take any action on the emails that fail the DMARC check.
- Optionally, you can click on Advanced Options to customize your DMARC policy further. You can specify the DKIM identifier, the SPF identifier, the policy percentage, and the action to take on emails that fail the DMARC check.
- Click on Add DMARC to generate the DMARC record for your domain.
- We’ll add the DNS record automatically for you, it’s added as a TXT record with
_dmarcas the host name.
You have successfully added a DMARC record for your domain using the DMARC Wizard tool. You can now monitor the DMARC reports and adjust your policy as needed. For more information on DMARC, please visit https://dmarc.org/.
