Hi, I have this situation
2 postfix accting as a relay for domain.com and 2 internal exchange servers as mailbox server. I have MX records pointing to both postfix servers, so if one is down the message is sent to the other. I want to do the same for internal servers, so I would like to now if it´s possible to set primary and backup internal servers on the transport configuration file domain.com smtp:[10.10.10.10] domain.com smtp:[10.10.10.11] When I use this sintax I have this message from postmap postmap: warning: transport.db: duplicate entry: domain.com Conrado _________________________________________________________________ Faça transações bancárias de maneira segura.
