SECURE EMAIL DELIVERY

Secure SMTP solution for legacy systems and printers

Legacy accounting and document-management systems and multifunction printers often do not support Microsoft 365 Modern Authentication. SMTP365 is a secure Azure-hosted SMTP relay that lets them send email through real Microsoft 365 mailboxes.

WHY SMTP365

Legacy compatibility, Microsoft 365 security

Keep working devices and applications while retaining controlled, encrypted email delivery.

Works with legacy applications and MFP devices

There is no need to replace an accounting system or printer solely because of email authentication.

Encrypted and restricted connection

STARTTLS or SSL, separate device credentials, and access restricted by public IP address.

Isolated companies and tenants

Each company’s Microsoft 365 environment is isolated from other customers.

Messages remain in your mailbox

Messages are sent from a real Exchange Online mailbox, with copies automatically saved in its Sent Items folder.

Centralised management

We can centrally manage access and securely review usage logs.

Clear deployment path

We assess the device, mailbox and network connection before integrating the solution with the live environment.

HOW IT WORKS

A relay between a legacy device and Microsoft 365

The device or application connects securely to SMTP365. The service checks the device credentials and public IP address, then relays the message through your Microsoft 365 mailbox.

This keeps delivery history in your company’s Exchange Online environment without requiring the legacy system to support a new sign-in method.
