🔒 What is DKIM? The email "security lock" for Microsoft 365 users

📌 DKIM (DomainKeys Identified Mail) is like a digital signature for your email. It proves the message really came from you and hasn’t been tampered with by malicious actors.

✅ How it works:

When you send an email, the system automatically adds a hidden digital signature. When the recipient receives it, their system checks your "online ID" (the public key in your DNS) to verify its authenticity. If it matches, the email is considered genuine and trustworthy!

✨ Benefits:

🛡️ Prevents spoofing: Scammers can’t forge emails from your address 📥 Avoids spam folders: Emails are more likely to reach the inbox 💼 Boosts professionalism: Clients trust you more when they see verification marks

⚠️ Note:

An administrator must configure the key in DNS (technical assistance may be required), otherwise DKIM won’t work!

🎯 Summary:

DKIM helps protect your brand image. Want your emails to be safer and more professional? DKIM is a must-have tool.
