SES send-path verification for the listmonk evaluation host.
If you are reading this in a mailbox, the whole chain works: listmonk -> SES SMTP
(us-east-1, derived credential) -> delivery, signed by the dedicated
list.youniqueproducts.com identity.
Two things worth checking in this message:
Authentication-Results shows
dkim=pass, spf=pass and dmarc=pass.
SPF should reference bounce.list.youniqueproducts.com, not amazonses.com.
