Hi,
You need to double check your EMAIL CAMPAIGN configuration wizard. There in the “Marketing” tab we can set all these things.
Please check the values for
From Name & From Address (FROM this address you should receive emails)
“Reply-to” Name & “Reply-to” Address (This should be included as Reply To in received email)
Bounce Handling is not Reply To and Outbound Email Account is not From. These are being handled by the fields i have mentioned above.
