Exchange Advice: AV and Postini
Posted on 2009-12-16
We're in the planning stages of migrating to Exchange 2007 from our current mail system. We currently use Postini for all filtering (spam and AV). We don't currently run any mail-intergrated AV on our mail server, just Symantec Endpoint Protection. I'd just like to get some expert opinions on whether something like Symantec Mail Security is still good to have alongside Postini, or if it's really redundant and a waste of system resources (single-server installation).
The system will be a single Win2003 Server running Exchange 2007 for under 100 users. As mentioned, Postini provides our inbound filtering.
