Currently we have a legacy Axway Mailgate clustered appliance that sits in our DMZ that buffers mail between Exchange on premises and Mimecast cloud services (i.e. external send, receive, SPAM control, and message hygiene). I have considered replacing Mailgate with the Exchange Edge Role, but I don’t see the value add considering what Mimecast already provides. I don’t really want to forward Mimecast traffic thru my firewall to my internal exchange servers directly. A simple DMZ hardened Windows Server 2008 SMTP relay seems like a plausible option. What is your best practice recommendation for that buffering link between Mimecast cloud, and Exchange internal?
