Now, in Exchange 2007, and following the RFC 2298, the Out Of Office implementation leave the envelope from field empty, and this is causing that my external relays don’t let this mail travel to internet.
I understand that perhaps technically it’s better not to send these messages to Internet but my boss doesn’t think so.
I don’t want to change anything in my relays, so my intention is to create a transport rule that fills this “from” field with a generic address of my organization. I have tried with the action: “set header with value” but I don’t know how to access to the envelope “from” field.
Any ideas? How can I fill this field????
Thank you in advance.
