It is not the errors themselves that are sent to the admin list.  it
sends notification about devices added/removed (which is duplicated
to the diff list in diff form of router.db) and when the age of a
device's collection exceed rancid.conf(5):OLDTIME time.  Off the top,
that is all that goes to admin.
