Hi all, I have a server I built following the LAMP for FC6. What I need to do is setup Postfix to be a store and forward for our exchange server so that we have a backup in case the server goes offline for any reason. I have a doc I am following, but noticed that some of what it calls for doesn't exist in this setup. For example, cp /etc/postfix/aliases /etc/ fails because the aliases is missing from that directory. I don't use postfix for any of the sites I have on the box since they are strictly in house use, and we have an Exchange for our mail. What can I do so that this server will accept all mail for our domain and be able to forward it off to the Exchange server when an outage occurs? EDIT: I would also like for this server to accept mail for two other domains we host email for, those two are Exchange 2007 servers.
