Use in Spam Control Efforts
Some ISPs, in an effort to reduce email spam originating at their customer’s IP addresses, will not allow their customers to communicate directly with the recipient’s mail server via the default SMTP port number 25. In this case the customer has no choice but to use the smart host provided by the ISP.
When a host runs its own local mail server, a smart host is often used to transmit all mail to other systems through a central mail server. This is used to ease the management of a single mail server with aliases, security, and Internet access rather than maintaining numerous local mail servers.

“The mind is the greatest of all human forces. Control the mind and you control the body.”
—Griffin Jay, Randall Faye, and Lew Landers. Armand Tesla (Bela Lugosi)
“Every new stroke of civilization has cost the lives of countless brave men, who have fallen defeated by the “dragon,” in their efforts to win the apples of the Hesperides, or the fleece of gold. Fallen in their efforts to overcome the old, half sordid savagery of the lower stages of creation, and win the next stage.”
—D.H. (David Herbert)
