If you run fetchmail with the -v option, you will see very clearly that
(a) is just not true. If (b) is the answer, then your DNS must have been
pointing at the old machine (not either of the two new ones) and they
seem to have stopped their pop server, deleted the mail spool, and then
re-started the pop server on that machine. Not a very kind thing to do
to their customers (in my opinion). Having two computers share a RAID
system for load balancing, sounds like both machines can access the data
on the RAID system at the same time, so it shouldn't matter which of the
two computers your DNS points you at, you should see the same data --
hence the load balancing (of the computers -- I assume).
The question I would be asking the ISP is: how did they move the mail
from the old machine to the new configuration? From what you have
described, I'm a little suspicious that they might not have moved
anything (and hence your sudden loss of mail). I don't mean to be
alarmist, just trying to explain the thoughts that are running through my
mind.
