I ended up doing the dpkg-reconfigure exim4-config
command mainly just to see what questions it asks and it is not
bad at all. If you want to go through it again, the previous
choices become the defaults so one can just hit Enter for most
of the questions. Your example was good to compare with but I
figured that I needed to go through the whole configuration
since what you start with after installing wheezy does not
include /etc/exim4.conf.conf.
I'm now getting mail from all over and need to get
procmail working on this system to bring some sanity to the
torrent of messages coming in, a lot of which are from the mailer
daemons on systems trying to deliver mail over the last couple
of days.
Thanks for all the help. I will save the messages for
future reference.
