Hi, I have a postfix (2.5.5) setup used both to send/receive our company e-mail and at the same time a few mailing lists (managed by sympa on another domain).
Let's say I want to "separate" both outbound traffic, by binding the smtp sender daemon to a different IP address depending on if I send corporate e-mail or an e-mail from the mailing lists. I know how to define a transport to do that, but the next-hop is chosen by looking-up the destination domain (which makes perfectly sense) and not the source domain. How is it possible to chose the transport from the source domain? Is multi-instance my only chance? Thanks for the answer, -- Brice Figureau My Blog: http://www.masterzen.fr/
