Just a note about the parsing of boolean options, having debugged someone
else's config file. Exim quite happily accepts lines of the form
freeze_tell_mailmaster = false
but it seems that this actually sets the boolean to true. Of course, in this
case the administrator should have written
no_freeze_tell_mailmaster
However I think that Exim ought to produce an error (or at least a warning)
in the first case, to cope with administrators who have not quite read the
documentation fully :-)

Brian.
