About Email Spam Filtering
For M365 and more!
Protecting your inbox is more than just blocking junk—it’s about stopping threats, preventing data leaks, and staying compliant. Whether you’re using Microsoft 365 Basic, Standard, or Premium, or layering in Hornet Security, we offer flexible solutions tailored to your needs. From tightening built-in filters and enabling secure message encryption, to advanced DLP policies and full email continuity, we help you choose the right tools—and configure them properly. Many powerful features are included in your licensing, but to work effectively, they require setup and tuning, which we handle as part of our hourly service.
📧 Email Reputation & Delivery Fixes
Fix email going to spam or getting rejected
Even with Microsoft 365, issues like missing SPF, DKIM, or DMARC records, domain misalignment, or IP reputation can cause deliverability problems. We audit and correct your domain’s DNS records, help you pass email authentication checks, and clean up any blocklisting or bounce-back issues. This is a one-time or as-needed consulting service.

🛡️
🛡️ SPF, DKIM & DMARC Hardening
Build trust and prevent spoofing
Microsoft provides basic SPF and DKIM defaults, but these often need custom tuning. We implement or refine your SPF, DKIM, and DMARC policies to align with your brand and domain configuration. We also advise on moving from “none” to “quarantine” or “reject” policies safely.
📊 DMARC Reporting & Monitoring
Visibility into who’s sending from your domain
While M365 supports DMARC policies, it doesn’t include easy reporting tools. We set up DMARC report forwarding and recommend third-party dashboards to visualize who’s sending as your domain — helping you catch abuse, spoofing, or unauthorized relays.

🧰
🧰 SMTP Troubleshooting
Solve bouncebacks, misroutes, and server issues
If you’re seeing “message rejected” errors, DNS lookup failures, or TLS negotiation problems, we can help. We diagnose SMTP configuration issues inside and outside of Microsoft 365, including hybrid environments and third-party mail senders.
🔁 Legacy Email System Cleanup
Resolve DNS and sending issues from past providers
Many clients carry baggage from previous systems — old DNS entries, duplicate SPF records, or misconfigured MX priorities. We clean up and modernize your domain’s DNS so your Microsoft 365 setup works as intended.

🔑
🔑 Email Migration Support
Smooth transitions to Microsoft 365
We offer full-service email migrations from G Suite, cPanel, GoDaddy, or Exchange to Microsoft 365. Includes mailbox setup, data transfer, and DNS cutover. We minimize downtime and preserve your data — all with white-glove support.
