Email Security

Intragreat sets up email security for startups, mid-sized companies, and small IT teams on Microsoft 365: SPF, DKIM, and DMARC moved to enforcement, anti-phishing tuned, and mailbox-rule monitoring to catch account takeover. It’s the layer that stops domain spoofing, wire-fraud emails, and the “your CEO” phishing that targets fast-moving companies.

FAQ

Common questions.

What do SPF, DKIM, and DMARC actually do?

They’re three DNS records that let receiving mail servers verify your email is really from you. SPF authorizes which servers can send as your domain, DKIM cryptographically signs your mail, and DMARC tells receivers what to do with messages that fail — and reports who’s sending as you. Together they make your domain hard to spoof.

What does “DMARC at p=none” mean, and why is it a problem?

“p=none” means DMARC is in monitoring mode — it reports spoofing but enforces nothing, so anyone can still send email as your domain. It’s a fine starting point but a poor resting place; the goal is to move safely to p=quarantine or p=reject so spoofed mail is actually stopped.

Can you stop business email compromise and wire fraud?

We make it much harder and easier to catch. Email authentication and impersonation protection cut the fraudulent messages that reach people, mailbox-rule alerts catch the forwarding tricks attackers plant after a compromise, and we help you put a callback-verification habit around payment changes. No control is absolute, but this combination has the strongest track record.

Will enforcing DMARC break our email or newsletters?

Not when it’s done carefully. The reason to move gradually — and to inventory every service that sends as you, like your CRM or newsletter tool — is precisely to avoid breaking legitimate mail. We use DMARC’s reporting to confirm everything’s authenticated before turning on enforcement.

A mailbox was compromised — can you help?

Yes. We review sign-ins, mailbox rules, forwarding, and delegated access to understand what happened, lock the account down, and check whether it was used to reach other systems or send fraud. We’ll also close the gap that allowed it so it doesn’t recur.
