AWS Send Email not authorised for "noreply" emails

Lambda is authorised to send emails to my domain. This works for all email addresses in that domain except for "noreply"

The domain AND noreply email address are verified identities in SES also.

Error message

"User [LAMBDA] is not authorized to perform ses:SendEmail on resource arn:etcetcetc:identity/noreply@example.com}
