Only if you tell them to do so. By default dig and nslookup do the query
to the same resolver IP that the system libraries use.

If there is a cache in use, it is inside the Evolution libraries. If a
command-line ping, dig, or host command returns the new IP for a DNS
name, Evolution should be using that as well.

If it does not, that would be a bug. Because IP addresses do get changed
now and then, and users with laptops rarely close email programs when
you can just leave programs open and suspend/resume the machine.
