I have created a Sender Profile with custom reply-to name/address fields defined. When doing a send preview you can clearly see the values differ from the From Name/Address fields however when I receive the email and try to respond, it responds to the From Address.
It should be noted I've disabled RMM, by unchecking "Has DNS been updated".
Can anyone explain why my email sends don't have the correct reply-to addresses?
Edit: Added screenshots to show what settings have been used, redacted part of the domain and sender names.
