Wietse, Could you please tell me the difference of "same host" and "myhostname"? What I understood from the document is that its suggested to use the same host/ip to re-send the message in cases of greylists. In my case, each postfix server uses myhostname to determinate the server's host (each host has its own ip). So I imagined that I should use the same myhostname in smtp_fallback_relay in order to have it retrying to send the messages that were deferred because of graylists. Would you please give me a light on this? Thanks in advance. - Rafael
