We use both RMM (MC) and email2case (SC), only we experience an issue.
When somebody replies on an email that is sent from Marketing Cloud. Their reply is forwarded with RMM to the address [email protected]. This triggers the email to case, a case is created.
The only problem is, the email address of the contact on the case is re-written from [email protected] to [email protected]. Therefore, a new contact is created, instead of connecting it to the existing contact with the email address [email protected].
Does anybody have a solution to this?
As far as I understand, disabling DMARC forward reply re-write will give issues with forwarding the emails at all. https://help.salesforce.com/articleView?id=mc_es_dmarc_fwd_reply_rewrite.htm&type=5
