2,400+ members to exchange operational messages via SITA Community Messaging

How it works

Message Relay ensures that messages sent from SMTP, when converted into Type B, are fully processed by receiving applications. In return, complex Type B messages can be received direct to your desktop in an easy-to-use format.

Message Relay protects your email using state-of-the-art address mapping, domain hiding, anti-spam and anti-virus filtering. Message Relay also offers access via private IP as well as the internet and a secondary relay for backup to existing email servers.

A virtual private network (VPN) or public IP (internet) connection is all you need to exchange information reliably and securely with all your business partners.

Your benefits

Message Relay reduces your cost of ownership because it works with your existing email application. It handles high-volume traffic and enables transparent mapping and conversion between SMTP and Type B messaging.
