The latest update adds support for a new protocol called ARC (Authenticated Received Chain), which is designed to help mitigate SPF, DKIM and DMARC verification failures by allowing mail transfer agents to reuse and resign the original email authentication results as the email traverses through the network.

You can download it from the Client Portal:

Great work, we have now installed the new version.

I have however a small anomally.
We run ORF on 4 edgeservers and looking into ORF locally everything is ok and green status.

But, we connecting remote to an installation on another edge we get an error in status claiming that the signing agent is not running.

I have confiremd that it is running by checking every edge locally through ORF and get-transportagent.

So my question is, does anyone else experiance this?

Hello Ola,

Is the affected ORF installation running on Exchange 2010 by any chance? If so, please consult the KB below and let me know if the suggested workaround fixed the problem.

In addition to the above, please verify that the "file version" of the installed "ORF components" on the server are identical ( ORF Administration Tool > Help > About ORF Fusion > Modules ...

I am looking forward to hearing from you.

@ola.dahlback: Never mind, we have also managed to reproduce the UI bug on our side. Fortunately, this is only a "cosmetic" error and the configuration can be edited and saved remotely. We are going to fix this in the next patch - which is already in the works and should be out in a week or two.

Thank you for reporting this issue Ola!
