Advanced Routing
Sender based smart hosts allow you to relay outbound email from a particular domain or email address through a specific relay or smart host. Go to System Setup > Mail Relay > Advanced Routing to add, edit or delete a sender-based smart host.
Note
If you want all outbound mail to go through a particular mail server, specify those smart host details in the Enable Smart Host: setting on System Setup > Mail Relay > Outbound. Sender based smart host entries override those settings for the specified domains or email addresses.
