SPF changes on this the emails are still comingin via mta-bbcspool.convio.net. Is this normal?
Yes. This is normal behavior, because Luminate Online uses mta-bbcspool.convio.net as part of their outbound mail servers. The SPF record is what allows email to be sent from the organization on Luminate Online servers, but the email themselves get sent by Luminate Online servers which is why it says via mta-bbcspool.convio.net.
