Inter domain outbound email

[dcol]

Does Smart Host or any other method allow internal email to be passed through an external server?
What I want to do is have all outbound or inbound email from user1@mydomain.com to user2@mydomain.com pass through another server. I know how to do it for external addresses but that doesn't handle internal email.

Hi,

MailEnable will always try to deliver locally if the domain or mailbox exists. There is no option to route local delivery via an external SMTP Server.

There should be when using smart host. I would like to see all outbound email sent to a dedicated SMTP IP.
