I have a SmarterMail 11 system with several domains running on it. We have the requirement to route all outbound mail for a single domain through an outbound gateway. I can see under Settings--Routing--Outbound gateway I can configure an outbound gateway, but I only want e-mails from this single domain to use this.
How can I accomplish this? I don't want any other domains to use this outbound gateway just the single one.
