The latest and greatest version of ORF is now available: the installer can be downloaded from the Client Portal section of our website after logging in.

ORF 6.6 adds support for a new email authentication system called ARC (Authenticated Received Chain), which is a novel protocol coming down the standards pipeline intended to solve email delivery issues caused by intermediate mail servers that render SPF, DKIM or DMARC invalid in emails.

For detailed information regarding this release, please consult the ORF Change Log.
