In upgrading to the latest version of SmarterMail the gateways are no longer routed by 1-10 priority which is fine at the domain level, but it seems I have lost the ability to route specific senders through specific gateways. Can you add back this functionality by allowing a sender address to be associated with a specific gateway? For example if there is an address that sends transactional email vs one that sends bulk or marketing email I would like to use different gateways for these and I could do this before but as far as I can tell there is no way to do that now that the priorities have been removed.

Thanks,
Colin
