I'm running Norton Antispam in MS Outlook 2013 on a Windows 8 platform. It's always worked well, filtering out about 90% of the spam I receive across all my accounts, ~800 to 900 emails a day. I recently moved and went from a 1.5mbps DSL connection to a 20mbps Fiber connection. Now, with the much faster connection, NAS can't seem to keep up and is only filtering ~5% of the spam, leaving hundreds of emails in my inbox each day. The only change was the connection speed. Is there a way to tweak NAS to slow things down for it, or speed it up?
