Microsoft Gets Serious About Email Security
Microsoft has introduced new rules for high-volume email senders, tightening security requirements to align with email giants like Google and Yahoo. If your organisation sends more than 5,000 emails a day, you’ll need to comply with these new standards or risk running into trouble.
These changes are designed to prevent phishing and impersonation attacks while improving email trustworthiness. For Australian businesses, this isn’t just a tech headache – it’s a practical change that could boost operations and protect your reputation if handled correctly.
Why DMARC Matters
The backbone of this update is DMARC (Domain-based Message Authentication, Reporting, and Conformance). If you’re wondering what that means, don’t worry, you’re not alone.
DMARC works alongside other protocols like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate emails. Essentially, it’s a security system that ensures emails claiming to come from your organisation actually do. This means stronger defence against scams, less chance of important emails getting flagged as spam, and a better email reputation overall.
The tricky part is that if your systems aren’t compliant, things can escalate quickly. Emails might stop landing in inboxes, vital communications could be missed, and campaigns might fall flat. It’s not just about IT systems – poor deliverability can shake client trust and disrupt daily operations.

Who Needs to Pay Attention?
Microsoft’s updates touch more than just the IT team. Every department that relies on email will feel the impact, and it’s crucial that organisations approach this together.
Here’s how it affects key players:
- Leadership Teams: If emails aren’t delivered, relationships with clients and stakeholders can suffer. This isn’t just about security; it’s about keeping the business running smoothly and protecting its reputation.
- Marketing Teams: Campaigns rely on reaching inboxes, not spam folders. Failing to adapt could mean wasted effort and missed KPIs.
- IT Professionals: You’ll be at the heart of this, ensuring technical integrations are handled without disrupting the day-to-day work of the business.
Beyond internal challenges, cyberattacks like domain spoofing are on the rise. Ensuring compliance doesn’t just streamline communication; it puts up a solid barrier against security threats.
