Feature highlights

Gateway-less integration

ORF integrates directly with Microsoft Exchange and the IIS SMTP Service - you don't need to reconfigure the mail flow and firewalls, just install THE ORF and it works immediately.

Transport filtering

ORF SMTP transport-level filtering allows you to stop threats directly and can save server resources. The ability to return emails during transmission also enables proper handling of the NDR in compliance with standards and prevents backscattering issues.
