Persist header data across reply emails
- by mickyjtwin
Am trying to determine the best way to persist information from an originating email, through to a reply back.
Essentially, it is to pass a GUID from the original email (c#), whereby when the receiver replies back, that GUID is also sent back for reference.
I have tried setting the MessageID, whereby using Outlook, the In-Reply-To value is set with the original ID, however using some webclient email systems, that value is not created on reply. Is there another way to sent this info through email headers?
