Martin - another part of the program sends an email back to a
specified user, and that works, so LocalSystem must at least have some
network access.  From the testing I've done so far, seems like there's
just some grey area (which I haven't completely figured out yet) of
network-related tasks that LS just can't do.  I'd love to know what
this is, but so far the solution I have is just to create another user
and have the service use that..
