Spooling Mail Server
Hi,
I'm hoping someone can help me with the following issue. Bear with me if I don't get all of the terms exactly right, as I'm not 100% on the terminology... I'd like to set up a backup mail server that can accept email for a domain if the primary mail server (which is an MS Exchange Server) goes down. This server would accept all email, and store it locally until the primary server becomes available again. Once this is available it would then forward all the messages to the primary mail server. I think this is called a spooling server? I would prefer to use postfix for this if possible, but am open to suggestions. Thanks, Tom |
that would be quite simple in general. there may well be template configs out there for that use, but essentially it would be a default installation that happens to have no local delivery. if you do percieve prolonged outages you should be able to modify the retry and expiry intervals for it's relaying to other servers. just set the server up to relay for the end domain, and pretty much ignore the rest. i've not touched postfix before, but this doc looks nice and concise (yay google...) http://www.akadia.com/services/postfix_mta.html particuylary the "Mail transport switch (Mail Proxy, Mail Gateway)" section.
