MailEnable will not use the smarthosting rule if either of the following is true:
1. A catch-all has been defined for the domain that is being smarthosted
2. Address maps (E-Mail addresses) for the domain being smarthosted are assigned to the mailboxes for the domain.
Hence, MailEnable will satisfy local delivery requirements before the smarthosting rule is applied.
Also, MailEnable's SMTP Connector knows when a domain is smarthosted and will accept e-mail for any address for that domain. If smarthosting is disabled this will produce a 550 error (because unless the domain is smarthosted, or a catchall is defined or an the target address has been assigned to a MailEnable mailbox).
