How it works

Email Flow

Stop All Email Threats

Your incoming mail is directed to our global network of spam fighting data centers.

We scan your email for spam, phishing attacks, malware and viruses. All offending mail is held in secure quarantine in our network. Your users can receive a quarantine report containing recently stopped messages, or view quarantined messages online in real-time.

Clean mail is automatically forwarded to your server for delivery.

MX Guarddog offers complete email security, with no software to install and no changes on your email clients. Our hosted service protects your email against:

  • Spam
  • Computer viruses
  • Malware
  • Phishing emails
  • Spoofed undeliverable notices
  • Denial of Service Attacks (DoS)
