macos sequoia mail reply-to address always overwritten with account's primary email

Sending apple mail on a brand-new base model MBA.

Primary apple account address is a non-apple email address

Secondary apple account address is an iCloud address.


I want mail sent from the secondary account to have a reply-to of the secondary account.


But...


Mail sent from the secondary address *always* has a reply-to the primary address.


I've tried setting it manually in the message as per apple support page.

I've left the field blank

I've forced the "send new messages from" to the secondary address in the settings->composing page

I've tried a few other things from around the web, like "sudo write defaults com.apple.mail..."


You can see in the Sent folder, the reply-to address is *always* the primary address.


Tearing my hair out.


Please help prevent premature baldness...
