You can specify a delivery path that may be faster and less expensive than a direct link. Type the fully qualified domain name (FQDN) or IP address of the server through which you want to route messages for this remote domain. If you enter an IP address, enclose the address in brackets ([ ]) to improve system performance. This setting overrides the smart host setting on the Delivery tab.
To designate a route domain
Right-click the SMTP virtual server, point to New, and then click Domain.
Use the New SMTP Domain Wizard to create a remote domain. In the results pane, right-click the new remote domain, and then click Properties.
On the General tab, under Route domain, select Forward all mail to smart host, and then type the FQDN or IP address of the server through which you want to route messages for this remote domain.
Note: You can identify the smart host by FQDN or an IP address. (If you change the IP address, you have to change the IP address on every virtual server). If you use an IP address, enclose it in brackets () to increase system performance. The SMTP service checks first for a server name, and then for an IP address. The brackets identify the value as an IP address, so that the DNS lookup is bypassed.
