Ok, this seems to be a really big area so I dont mind asking for a few pointers before I get started.

We have had some email outages in the last few months and my boss is asking is it worth going with one of those email redundancy/filtering sites. The thing is, we have a backup server on a remote location, so I am pretty sure we can set something up with what we have already.

At the moment I have the top MX record pointing to my in-house server and the next entry for our dedicated (off-site) server in a data center. I was thinking that instead, we should have the first record pointing to the off-site server, which would save all emails and then forward them on to the in-house server. That way we would have backups etc. In the event of that server going down the in-house one would take over.

The off-site server is linux and the in-house is SBS. Is this possible, and are there any resources out there to help me?
