Exactly. You'd probably want to set up Bind to forward DNS requests to
your regular internal resolvers and also put them in resolv.conf,
*after* 127.0.0.1 (for times when your caching nameserver isn't
running).

A filesystem that lives solely in virtual memory (physical or swap,
depending on memory usage), so you're not using real disk I/O to dump
out the parts of the message to the 'scan' directory during exiscan
operations. See:
