OOMS and Remote Sites
I have a question regarding out of mail stream (OOMS) gateway placement of UN. We have a situation where a mail server is in a remote location over a WAN link and all users get their email via this link, and want gateway email implemented for a small amount of users. We don't want the UN to become a single point of failure (even when clustered) so want it OOMS. There is very little documentation regarding OOMS and setting this up - what's the best practice for implementing OOMS gateway placement of a UN?
