We are MX-Relay
From inbound filtering to full SMTP provider.
MX-Relay has started to protect incoming email. Afterwards, we have grown to SMTP services for reliable shipping. Meanwhile, we also help organizations to monitor their mail environments better and to respond to signals faster.
Growing from the practice of email security
Our services have emerged step by step from what customers needed: first better protection at the front, then reliable SMTP transmission for applications and Microsoft 365, and now also monitoring that shows what needs attention.
Inbound protection
We started stopping spam, malware and phishing before messages reach the mailbox. Reliable filtering remains the basis of MX-Relay.
SMTP-provider
Then we built SMTP services for reliable shipping: monitoring reputation, recognition of abuse and ensuring that systems can deliver stable mail.
Monitor365
Today we combine email services with monitoring, reporting and tracking for Microsoft 365 signals that need attention.

We keep our solutions consciously clear. No unnecessary complexity, clear logging, good delivery, practical settings and support that knows how mail flows work.
