A single machine should be able to do this in an hour. This not a high
volume. Two machines of any reasonable vintage will do the job. Scale the
CPU for any content filters, but peak loads of even 10 messages per hour,
are still just 3 messages per second, and 10-20 messages per second per
machine is common with A/V scanning, 40-200 without (depending on disk
bandwidth, battery backup writback caches, ...).
