twisted.mail.relaymanager

module documentation
(source)

Infrastructure for relaying mail through a smart host.

Traditional peer-to-peer email has been increasingly replaced by smart host configurations. Instead of sending mail directly to the recipient, a sender sends mail to a smart host. The smart host finds the mail exchange server for the recipient and sends on the message.
