Your Domain Could Be Sending Emails You Never Wrote
Email spoofing is one of the most common techniques used by cybercriminals. By sending emails that appear to come from a trusted domain, attackers can trick recipients into clicking malicious links, transferring money or handing over sensitive information. The recipient sees a familiar sender address and has no reason to suspect anything is wrong.
For businesses, this is a serious risk even if your own systems are never actually compromised. An attacker does not need to gain access to your email account to impersonate your domain. Without proper authentication records in place, they can send convincing emails in your name to anyone, and your clients and suppliers will have no way of knowing the message did not come from you.
DKIM, DMARC and SPF are the technical standards that address this problem. Together, they verify that emails claiming to come from your domain were genuinely sent by you, and they instruct receiving mail servers on what to do with messages that fail that verification. Getting these records correctly configured is one of the most impactful steps a business can take to protect its email reputation.
Email Authentication Configured Correctly
SPF and DKIM, Correctly Configured
SPF tells receiving servers which systems are authorised to send email on behalf of your domain. DKIM adds a digital signature to your outgoing emails that proves they have not been tampered with in transit. Both need to be set up correctly to be effective, and we handle that for you.
DMARC Policy That Protects Your Reputation
DMARC ties your SPF and DKIM records together and gives you control over what happens when an email fails authentication. We configure a DMARC policy that actively blocks spoofed emails while giving you full reporting on how your domain is being used.
Ongoing Reporting and Monitoring
DMARC generates detailed reports on every email sent using your domain. We monitor these reports, alert you to suspicious activity and adjust your configuration as needed, so you always have a clear picture of your domain's email health.
Technical Configuration You Should Not Have to Figure Out Alone
DKIM, DMARC and SPF are not complicated concepts, but getting the configuration right requires technical precision. An incorrectly configured DMARC policy can cause legitimate emails to be rejected, and a misconfigured SPF record can leave gaps that attackers can exploit. At AOIT, we handle the technical setup carefully and methodically, making sure your authentication records protect your domain without disrupting your email operations.
We also stay involved after setup. As your email environment changes, whether you add new services, change providers or update your sending infrastructure, your authentication records need to be updated to match. We keep track of those changes and make sure your configuration stays accurate.
What Our Partners Say
Has Your Domain Already Been Compromised?
Without DMARC reporting in place, you would have no way of knowing. Get in touch and we will audit your current email authentication setup, show you any gaps and put the right records in place to protect your domain and your reputation.
What are DKIM, DMARC and SPF?
Why do I need these records if I have not had any problems?
Without DMARC reporting, you would not know if someone were impersonating your domain. Many businesses only discover they have been spoofed when a client or supplier reports receiving a suspicious email in their name. By that point, reputational damage may already have been done.
Will setting up DMARC affect my existing email?
If done carefully, no. We introduce DMARC in monitoring mode first, which allows us to see how your email is behaving without rejecting any messages. We only move to enforcement once we are confident that all legitimate email is properly authenticated.
What is DMARC reporting and why does it matter?
DMARC generates reports that show every email sent using your domain, including emails sent by third parties who may be spoofing you. These reports give you full visibility over your domain’s email activity and allow us to identify and respond to misuse quickly.
How often do these records need to be updated?
Your authentication records need to be updated whenever you change your email provider, add a new service that sends email on your behalf, or make changes to your email infrastructure. We keep track of these changes as part of our ongoing management and update your records accordingly.
Is this relevant for businesses that use cloud-based email?
Yes, absolutely. Authentication records are managed at the domain level, not the email platform level, and they are relevant regardless of which email system you use. Cloud email platforms still require properly configured SPF, DKIM and DMARC records to function correctly from a security perspective.
