The email address that would appear as the From Address for the automatic reply to the customer is [email protected]. This is because Northern Trail Outfitters has configured their Reply Mail Management settings to forward replies to [email protected] and send an auto-reply message to the customer's email address. The From Address for the auto-reply message is always [email protected], regardless of the original From Address or the forwarding address.References:https://help.salesforce.com/s/articleView?id=sf.mc_es_reply_mail_management.htm&type=5
